Just came from mechanics and the car finally stalled for them. According to them the car is losing spark. Just before the car stalls the coil spark gets very weak and the injector pulse gets very weak. Does anyone have any ideas where to look for the culprit?

 

Pick up coil in the distributor?

 

That is what we are replacing tomorrow, the pick up coil that is.

 

i bought a used 89 iroc w/ a tpi 350 & everytime i would come to a stop the car would die(at idle)!i didnt have any codes come up either.i replaced injectors,plug wires,coil etc.nothing worked until i replaced the computer!!!now the car idles great.come to find out the previous owner put a 305 computer in it.if you have a spare ecm try it out or pick one up at your local salvage yard for around 20 to 50 bucks ..etc tanks bdcamaro

 

hey, maybe that'd solve my problem. my car will also occasionally die if it's left without a bit of thottle. as parts have broken on the car in the 30k miles, it's been that long huh, i've had it, the problem has gotten better. that problem, and starting, markedly improved when we changed the fuel filter and also when we had the alternator rebuilt when it died. now the problem is recognizable at startup by a weak pickup, engine starts but doesn't just jump into a normal idle like normal. when this happens i'm guaranteed that it will die when i pull up to the next stop, so, what to do. i've found that if i simply turn it off, which it wants to do anyway, pull the key out a click and put it back in, start the car, maybe have the fuel pump run for a min, the car will usually snap right into idle and i will have no problem. on a testy day it will mess with me for 3 tries or so, but i'm not worried cos it will eventually get going. and sometimes it does fool me and run ok, then all of a sudden go out. so i might try that computer thing if i ever have a chance to get a hold of one cheap, but for now, that's where i'm at on mine, maybe it'll help someone else out as well.
