We replaced the vacuum and coolant lines on Matt's '89 TII tonight, and it's still having all of the same problems. We checked the engine codes, and it came back with 30 Solenoid valve - split air bypass and 38 Solenoid valve - accelerated warm-up system and air supply valve, neither of which I know how to deal with. The good news is that his TPS code went away, but the car still runs rich enough to burn our eyes and has NO power. It idles fine, but we haven't checked the compression yet, so that still may be an issue. Anyone have any other ideas?
One thing that bothers me is that I could disconnect the O2 sensor while it was running and it wouldn't change anything, like it was in limp-home mode, but it didn't change after resetting the ECU.

Perhaps we should check the fuel pump voltage at idle, wot, etc...
Taking out the injectors would be too big of a deal, i guess. I'm just trying not to put Matt into the poor house with the rest of us...lol.
