About 3 weeks ago, it started skipping out once the engine got hot (driving 85mph for 45 minutes.) Then once I slowed down it died sometimes, in a seemingly random way.
Driving home from work the other day my car just died while driving normally, for fear of making the problem worse. I couldn't get it started again, so I had it towed to my storage unit, where all my tools are. Thinking it was a coil pack, I hooked a spark plug up to an old wire I had laying around (since the wires in my car are such a bitch) and tested both points on each coil pack. Getting good spark from all of them. Next, I pulled a spark plug and it was black as hell, so I went down to Oreilly and bought 6 new plugs and wires. It still idled rough, so we checked fuel pressure, which showed as a constant 38psi.
On the way from there to 280Z28's house, which is down the road, my car was jerking really bad under any sort of load (i.e. acceleration), and having a tough time idling too. Sam went and bought some fuel injector cleaner, and we dumped that in at his house (thinking the injectors were sticking, thereby killing the engine and blackening the plugs). I started it up and let her idle outside his house while we ate dinner. It idled for a good 30 minutes straight, so I thought the problem was fixed.
Then, on the drive home, it would get REALLY rough under any load (acceleration from a light, out of a turn, etc.)
I don't even know what to try. Something tells me it's a sensor somewhere mis-reading something, thereby causing the engine to miscalculate the mixture. It idles fine now, but won't drive.
Advice? :help:
