Engine Mechanical problem
2000 Dodge Neon 4 cyl Front Wheel Drive Automatic 174xxx miles
I have a 2000 dodge neon, it idles fast when you start it, then it surges, it is getting very bad gas mileage now also. I have replaced the throttle position sensor, the idol air sensor/valve, map sensor, cam position sensor, and intake duct. The car will do 50 mph down the highway without your foot on the gas pedal. When you disconnect the map sensor it will idol alright, still rough but not high or surging, thought the 1st map sensor was bad but I have tried 2 different brand new ones. I cant seem to figure it out. The computer at advanced auto parts pulls a " manufacture code"
