Thanks! So it turned out to be the little plastic tab, on the clutch pedal, that pushes in the clutch safety switch. It was gone.
Car started and idled for a bit then began running rough and shut off. Tank was almost empty so I added a couple gallons of premium and tried again. Now car will only rev limits at 2500 rpm and wont idle. Did some research and I am going to change out the MAF sensor.
Any suggestions would be great.
I'll just say that due to the car starting and running OK to begin, that the MAF may not be the issue. Idle is controlled by the IACV, a notorious problem in that the unit itself can become gunked up and cause issues, and the IACV harness also is notorious for corrosion issues and broken connectors. The pcv hoses connecting to the IACV can also become brittle/broken and be a vacuum leak.
Other contributors to the bad idle are vacuum leaks from cracked/missing vacuum hoses, and the pcv setup can become clogged/non-functional as well...all areas needing inspection as well as others. Corrosion of connectors and bad injectors are usually the two biggest issues with the Z32, but the other issues also carry a lot of weight so a complete inspection is best practice.
Again, the fsm has all the tests and such to help with idle issues and many others, a very necessary tool for these cars.
Hope this helps, good luck!
