Idle Problems

Question: I'm a new Fiero owner and I purchased an '87 with a 2.8 engine installed. It is a great car however I do have one little problem. When you start it up, cold or hot, it will shutoff. When you put it in gear the idle will pick up until you you put the shifter in Park and then it will shutoff. It only idles around 800 rpm. Please help!

Answer: This sounds like a dirty air intake system, particuarly the idle air passage.

It could also be the Throttle Positioning Sensor (TPS) or the Idle Air Control (IAC) motor. A scan of the engine would determine if a sensor is faulty.
