got me a PROBLEM and need to fix it quick

[falloutman2]

ok here it goes for a diagnosis 72 stang holly 650 dubble pumper and petronix ignition and coil well i was driving today and it started acting odd and of all things smelled diffrent. here it goes was going 40ish i felt it jolt a few times so i looked at vaccume and oil presure gauges they didnt move from normal place then looked at rpm and it was spikeing all over the place going from my average of about 2200 rpm at like 45 down to 200 rpm up to 1500 and then it droped to nothin and died and after i poped it in neutral it cranked back up by it self and died after that but it cranks fine and when i start it and at idle its fine kinda bc i noticed the rpm meter jumps a bit at idle now that it happend so i got me a new coil thinking hey i know the problem a 4 year old coil nope i was dumb same **** so im thinkin that petronix ignition under the distrib maybe, its puting gas in the inake so i dont think a carb issue but it has back fired do to the car dieing like it did before so maybe the diafram is about to go but wouldnt cause this problem to just spike and die and it does it after i drive about 10 miles or so warmed up and now its starting to do it at any speed i have a little valve clatter but i dont think that would be a problem its not loud and obnoxis just quiet and suttle im thinkg a spark issue checked battery its fully charged did idiot test on neg battery cable for alt its fine so im at a loss and nows not the best time to have crap break kinda low on the funds i can afford a new petronix II ignition and coil but dont want to get it if its not the problem and dont got a volt meter and even if i did wouldnt know what to do with it so any help at all here guy and gals or if ya want gimme a call 210 649-7806 ill be up all night swearing at it and being angry so... thank a lot for help guys and gals :40oz:

edit: sorry kinda long needed to vent and SORRY for spelling and periods and comas and things ya i went to college and just learned how do drink beer thanks UTSA

I would check timing first..

[Masshole]

I would check timing first..

i agree with Joe, do that and come back to us :mick:

[falloutman2]

well i dont have my timeing gun i lent it to some one and well forgot who i was thinkin it might be the ignition box thats in the distribuitor http://www.pertronix.com/ its the ingnitor ignition one and yes i did forget about timeing thank you

[falloutman2]

other than spark i really have no damn clue what it could be i know timeing but..cant check that till like thursday and it only happens when a load is on the engine going atleast 35 so i check mr spark plug and wire good spark so........... could that igmition box be screwing up to not give any spark then it dies goin like 40 i put it in netural start it get rps good and drop it in gear still goin like 35 then wont do it again after i start it for like 4 miles or so....... im confused.........and sad so very sad yes there is a tear im my beer

idk much when it comes to ignitions and things like that. but if it is the problem, you should switch to a MSD. but if the timing is off tho, it'll cause all different sorts of problems. if it didnt have an idol problem, then id say it was the ignition. hopefully Joe or someone else can chime in on this.

[falloutman2]

the only one id go with other than msd is petronix bc i had a mallory POS before and never again every 3 months that damn 200 dollar box went out for no reason i even took it to a rep and thay said it was odd that this is happening and it was installed correctley i do like msd but $$ this month has been short comeing for car mods bills and **** like that come first for me so... i to am lost on electrical more that 2 wires and im confused thats why i chose petronix easy to install and well.. idiot proof that means i can install it i tryed a msd on a friends car and i couldnt figure it out again thanks for input HELP ME HELP ME oh i feel so sad i cant figure it out

[speedfreak87]

the one way to check spark is to pull each boot one at a time and try to ground it to something metal (like a bolt) you can only do it in the dark so you can see the spark and see how strong it is.. other then that, timing is the only thing I could think of right now, and until yuo check that, diagnosing anything else would be pointless.. one thing you could do is start the car and try to adjust the timing a little in each direction and see if it acts better.. How many miles are on the timing chain you have in the car now?

ebay.. or some of the racing sites classifieds like hardcore50.com, corral.net, racepages etc.. they ussually have good deals on ignitions because people upgrade.

[falloutman2]

oh damn i think on the chain........round about 50k-55k i think i checked spark but like before is fine at idle just when a load on engin and goin 35 ish 40...................:( ya new coil and igniton will run me like 130 not bad at all so i can pick that up easy

it could have stretched and jumped a tooth.. as far as load, have someone put it in gear, (while standing on the brakes) and try to drive, it should put enough laod on it to check the spark without the car taking off.

[speedfreak87]

here is a 6al.. the guy might still have it, it was posted at the end of sept,

[falloutman2]

i did as per your instructions and kinda felt my way to better timeing i retarted it just a we bit seemed better rpm meeter just pingin a little less than before hope it helps thanks

[speedfreak87]

take it for a quick ride and see if it helped any. once you get your timing light check and reset the timing.. do you know what it was set at prior?

[falloutman2]

yes i do i wrote it down in the chiltons book some whare near the timeing section

[speedfreak87]

ok.

Deffinatly check timing before you mess with the ignition or anything else. sometimes the dizzy can get loose a little.

[falloutman2]

brb TEST DIRVE!!

[falloutman2]

ok well.......still problems its not dieing like before but the rps are still spikeing high and low so still kinda confused got blue spark and i noticed one spark plug wire comin from distrib the brass pice inside the boot was all blue and partley broken off so thats no good and kina black to......but now at idle its spikeing bad but not dieing thats new

[speedfreak87]

when was the last tune up? (plugs, wires, cap, rotor) I was super **** with that when I had my old stang and changed everything once a year..

[falloutman2]

wires like 5 months and same with cap rotor and plugs like a week

[speedfreak87]

sounds like you need new wires if one of them is burnt like that.

[falloutman2]

word

[speedfreak87]

replace the wires and see what that does. then check the timing.

[falloutman2]

well.... today i couldnt make it to an auto parts store so no wires but being a plumber i have copper up the wazoo so kinda put a pice of copper in the cap for the wire so it gets good spark, as for timeing im dooin that tomarow as i have found who has my light but i think i did allright yesterday for timeing i go it to whare it sounds correct and runs right but needs fine fine tuneing all and all it works good hasent got ****** with me at all today so that was a big + was also thinkin it might have jumped time in any case im probley goin to get a new chain from summet this week or one of those gears instead of a chain and THANKS AGAIN thank you thank you

If you are talking about a gear drive, I have one I could sell you.. I just have to find it (it's packed away) I'll let you know in the next ouple of days..

[falloutman2]

was lookin at gears and i need one that works with a hydro cam i dont have a roller, thanks for lookin and if its the right one for a 302 sb i will probley get them from ya and was lookin there are 2 diff sets usailly quiet and loud the gears are a bit louder i take it

and not to add insult to injury but... now my headlights are flashin and i have just put in a new hl switch and there still doin it so im thinkin a damn short.... well when it rains it pours i guess...........

[speedfreak87]

All I know is it's a pete jackson gear drive.. came out of a 92 302 block.


As for the lights, check every single ground you can find.. unscrew or bolt them and clean the contact area, and scrap it a little for better contact.. (easiest thing to do first)

[falloutman2]

ya was planin on dooin that this weekend and was lookin at it bc im kinda **** and took the dash off and saw a black mark on the 10gauge yellow (power wire?) comin from the hl switch behind the dash so im goin to cut it and put a new like a new pice about a foot in length hope that helps with gound cleanin and thanks masshole way to say high five for self esteem you know how to raise it a litte

[speedfreak87]

if the wire is burned, you might have a short somewhere.. and I can't help with that as I farm out electrical gremlins to my freind.lol! He loves chasing the bastards down, I personally don't have the patience..

[falloutman2]

ya was thinkin the same thing but it looked like that little burn mark had been there for about 20 years so signs of new wear so was thinkin groind wires as what you said and i dont think it will hurt anything to replace a porton of that wire

[speedfreak87]

nope, just do it right with solder and heat shrink..

[falloutman2]

if i can reach it with the solder gun thats what ill do

[speedfreak87]

let us know.

[my86gt]

about your light check the voltage coming out your alternator and see what you get, you should be getting between 12.5 to 14.0 volts if im correct

[falloutman2]

ok well come to find out its not timeing.... its ignition its just f*ed up somewhare either the ignition box a wire (many to choose from) or maybe a broken plug.........dont know......... and lights still screwed and my valve tappet is gettin louder.... not been a good day and i dont know how to check volts... sorry i know im throwin my self a pitty party but hey better to vent then scrap it bc im almost there

[falloutman2]

*edit well i replaced wired and checked plugs, runs better i guess?..........cant notice and plugs have about 600 miles on them and not cracked no signs of wear so A+.........

[falloutman2]

well that seemed to do it with new wires... timeing was off just a hair and front bowl was a little low and driverside was a little rich but i fixed all that seemes to run a whole bunch better............ that was really odd
