Question about 2002 Chevrolet TrailBlazer
I would suggest trying to retrieve codes, this would really help at least point to where the problem may be. I have seen several trailblazer come in for this same problem and the most common issues I have found are a bad crank position sensor and issues with anti theft. Both give you similar symptoms but will set different codes.

I would begin by looking at the fuses. Check for one labeled ECM or PCM... Those are the computers that control engine management. There are also fuses for the coil packs and fuel injectors.

Testimonial: "03 Envoy:My reduced engine power keeps happening. My car goes 20 mph. Changed throttle body, pedal, wiring. Need new thermostat. Car not heating up."
There are numerous things that can caise a vehicle to idle rough. Could be a throttle posistioning sensor. pcv valve, dirty fuel filter, worn spark plugs and wires, possible O2 sensor. If the vehicle has not had a tune up yet, I would recomend one. Even if it doesn't fix your issue, the vehicle is ten years old and probably needs on anyways. Start there, then rule out the cheaper stuff next. pcv valve and fuel filter, inexpensive and it's probably time anyways. If you are getting an engine code, stop in to advance auto. They'll plug it in for free. If your still having problems, you may have to break down and tajke it to a mechanic to get plugged into a real diagnostics machine.(probably run you around $100)
