Couldn't have said it better myself. '95, 148k, meticulously maintained. The last 9 months have seen new fuel pump, 3 fuel filters, air filter, IAT valve, IAC valve, coolant temp. Sensor, vacuum lines, and Berryman's B-12 thru the fuel system. Finally gave up and took it in for a full diagnostic at the f@*$ ing dealershp -- they found nothing wrong at all. Still, the warmer it gets and/or the longer it runs, the worse the stumbling idle and lower the oil pressure gauge reads. Only thing I've heard that I haven't tried is a possible plugged oil pickup screen. Sounds like a lot of fun to fix and, running full synthetic changed every 3k with filter, I don't know how likely that sounds. Damn.
Am going to drop the $70 on O2 sensor today and am prepared to be underwhelmed. Will post if any miracles happen.
