On my 1993 AERO - 5 speed, I was having the same problem where the TCS and check engine light would come on as soon as the engine warmed up. Resetting was shutting off and restarting. This would let the TCS disappear momentarily but not check engine. I managed to clear check engine by disconnecting battery for a few minutes. However, the TCS light comes right back on as soon as vacuum begins to drop such as depressing the clutch and the revs start falling. If I keep the engine revs up to about 1500 rpm as soon as I clutch then I nanage to keep the TCS light off.
I measured the OHMS on the bleeder valve and I get 29 to 30 Ohms when engine is hot. Today something new happened. The car was totally warm, ran for 30 miuntes. Stopped the engine for 5 minutes. When I restarted the engine it took off to 5000 RPM , I immediately shut her down. It seemed like something took over the throttle control. I removed the 2 fuses for the electronic throttle and am now running on permanent limp mode, which also means that starting the car is more difficult since I need to assist the accelerator pedal.
Other info, I have the old style ETB, I checked the part numbers as Anders outlined. I also have the black and white check valve on the TCS bleeder valve. I cleaned the throttle body which evened out the idle.
About a month ago the TCS would come on once a week. I also noticed the accelerator required more effort to depress. Other than that, the car flew. A year ago, the car went into permanent limp mode. I had to replace the TPS at the potentiometer/accelerator pedal. I installed a used unit in working condition and worked fine. My car has 228,000 KM (135,000 miles).
What could have caused the 5000 RPM on startup?
