Interesting way of doing it AVR2 and glad you got it torqued.
After re-torquing my manifold bolts, fixing the brake booster vacuum leak, and installing a new CKP, I thought everything was fixed. Took my wife and son on a 70 mile round-trip to my nephew's grad party. As soon as I got off the freeway after 30 miles the engine started loping real bad, smelled fumes, and wanted to idle down to almost nothing. There was no way I was going to let it die in traffic so at every light I revved it up a little in neutral.
Again, the same old heat related problem and it was 88 degrees while having the AC on. Gauges all read normal and had a full tank of gas. I almost took the fuel pressure tester I have, along with my tools, but there was no way I was going to work on it in front of my brother's packed house.
So started driving home when dark and a whole lot cooler (72). Seemed to just bog down a couple times right when I left until I got it up to speed. Then came home the whole way, even made a stop, and no loping problems at all. It's all heat related.
Afraid I'm going to have to throw a new front o2 sensor at it. I'd love to have that fuel pressure text kit with me when it starts loping and connect it to the fuel rail. As mentioned before it reads lean fuel mixture on my scanner when its loping. Kind of at a loss and the only thing I haven't replaced, besides the downstream o2 sensor and throttle body sensors, is the OE fuel pump assembly. I'll see If I can get the engine to lope in the next couple days, since it will be 90+ degrees, and take a reading before thinking about replacing the fuel pump.
