Engine Performance problem
1992 Pontiac Sunbird 4 cyl Front Wheel Drive Automatic 122300 miles
I've been driving this car after replacing the cylinder head for about a week now. The car had been sitting for some time before I bought it, so I was happy once I finally worked out the timing and got the car driving nicely.
I notice that when stopped at lights, it seems to idle pretty low, but it hasn't necessarily been a "problem." Then yesterday, coming down a little slope to a stoplight, I stopped the car, and the engine died on me. I started it right back up and proceeded to drive.
a little later (maybe a few miles at most) the car started stuttering. Gaining and losing power in little blips. I had to feather the gas a little just to make sure it didn't die at the lights.
I got out of the car once I reached my destination and left it running and popped the hood. Nothing was visibly wrong (though I see my coolant is leaking from a weld in an OEM part. That's something I'll have to fix later) so I started jiggling things. I SWEAR as soon as I jiggled the portion of the main engine harness that goes behind the engine, the engine died instantly.
Any ideas as to what is going on here? It's been driving fine for a week now and just out of nowhere starts up with this strange bucking/power glitch thing.
have the same problem?
