Engine Performance problem
2003 Mitsubishi Lancer 4 cyl Front Wheel Drive Automatic 110000 miles
well it started by the idle was real low (500- 600) almost cutting off. Then at stop lights it would idle down to 400 where it was barely staying cranked so I adjusted the idle on to of throttle clockwise and it didnt change the idle I rotated 6 times completely. Then I was told to clean my throttle plate for build up so I did looks brand new I used brake cleaner and tooth brush was told it wouldnt harm it. Then turned idle down 6 rotations. Just to make sure I didnt over adjust it. Then the car wouldnt start and stumble for 10 seconds the quit so I adjusted idle up now idles at 700- 1000 which is kinda in specs (600-800) but at stop light my idle was normal then it would drop suddenly to 500 for about 10 seconds then right back up to 1000 and I noticed that before stopping I let go of the gas it idle up to 1500 then down to 800 after a few seconds before I hit the brakes so now im just confused
have the same problem?
