91 Stealth TT has nasty misfire (I think)
Local Mechanics are clueless on this one. This problem developed suddenly if that's a clue. Start the car and the engine is misfiring at idle with no apparent (to me) rhythm. When you try to maintain a steady speed the car bucks, sometimes violently. But, if you floor it, it smooths out. I have replaced the plugs and plug wires. I had the O2 sensor, EGR, and PCV checked. I even had the ThrottlePositionSensor replaced after the local dodge dealer told me it failed its test. That did nothing but cost a lot of money. I'm looking for a solid mechanic referral in south central Oregon (I'm in Grants Pass) or some diagnostic guidance. HELP!
Sounds like you may have a bad fuel injector causing a misfire,
