Ok, so I've got a "new" 91 325 auto. Bought in January with a broken timing belt. Replaced the head with a refreshed one, all new gaskets, t-belt, water pump, etc. Ran perfect for about 2-3 weeks. Then out of no where it stumbled at idle one day. Threw it in neutral and brought the rpms up and all was good. Let it idle for a while after and no issues. Then ~2 days later, same thing happened. The next time I went to start it, it took 2 long attempts to get it going. Just cranked and cranked but wouldn't catch. It finally did and ran great, no issues. Weird right? Well I drove it ~15minutes, turned it off for ~2 minutes, went to restart and it wouldn't. Same thing, cranked and cranked but nothing. If I put the pedal down, it cranked faster, but still nothing. I tried ~10-15 times and got no where. After letting it sit for ~10minutes, it started right up, ran fine, no issues.
This happened a few times, but it's started up quicker. I then swapped in a known good icv and afm, and it was good for ~2 weeks. It has now stumbled and stalled 3 times in the last 2 days. It's pissing me off, mainly because I cannot tell when it will happen. It is so random and unexpected I cannot duplicate it when I have the time or tools to figure out what's wrong.
The only thing that definitely is common with everything, is that the engine is warmed up, and its above ~60degrees outside.
I am at a loss. Does anyone have any ideas at all?
