Hello everyone,
I have a 1989 GA16I (w/CA emissions), 151,000 mi, that has developed an extremely bad habit of jerking/twitching when going down the road at speed, it doesn't do it under acceleration. Rarely is it hard to start.
Occasionaly it stalls when it idles down at a full stop. The strange thing about this problem is that it only happens when it gets hot outside (above ~70F). I am thinking that it could be some sort of thermal breakdown with the coil? I have replaced plugs, wires, dist cap and rotor, air filter and fuel filter.
The car does not overheat it operates midrange on the temp guage. If I were having this problem with my Fiero I would go directly to the ignition module but according to Haynes this thing doesn't have one (that I can find).
I have checked all the vacumm lines, and electrical connectors, didn't find any problems. When the driving the car and it starts jerking (doesn' happen all the time only when hot out) it is almost as if the car is stalling out and because it is moving it is restarting itself much like a push start.
I don't think it is the cat, had this same problem last year and by the time I got annoyed enough to do something about it the problem subsided because it cooled down. I had an emission test done about 3 months ago and it passed with flying colors.
Any help would be greatly appreciated.
Thanks,
Jeff
