I'll start with a little background, the car is a 1991 n/a, and was running fine when it was aquired. I was able to use it longer than I figured I'd have been able to living up here in michigan.

The problems started towards the end up when I was driving my car, in late october/early november. The TPS went out. I had the part shipped here not long after that. I put in on the car, and it started to run/idle like normal. It was just idling a tad high, at 1,500RPMs. I adjusted the Idle, and found that any time it dipped below 1,500RPMs, there was a vac. leak. I started checking the obvious spots, and couldn't find any lines that need replacing.

I changed the gaskets inbetween the the manifolds, and still nothing changed...so I let it sit until recently, when it was finally warm enough to actually start working on my car again.

I checked everyhing over, and started it up. As soon as it started, trouble began. The check engine light came on instantly, and the car stalled.

I pulled the codes, and found the following(when I put the car away for winter, there were NO codes at all.)

8) AFM
10) AFM Thermo
11) AFM Thermo (Engine)
12)TPS Full Range
18)TPS Narrow Range
25)Solenoid - PRC
31)Solenoid - Relife
32)Solenoid - Switch
40)Aux Ports - Valve
41)Solenoid - VDI
