Engine Performance problem
1995 Saturn SL1 4 cyl Front Wheel Drive Manual 196000 miles
I have had an intermittant problem of stalling, rough running, reduced power for around 4 months now. I took it to a shop originally because the idle would not go below 2000 rpm. The shop said it was the IAC. They said it had no vacuum leaks and no codes, even though the check engine light would always come on when it ran rough, stalled, etc. They did clean the throttle plates. I did some research and decided it may be the thermostat as my temp was always low. I changed the stat and it ran fine for about a month. Then I started getting the rough idle, stalling, reduced power problem again. The engine has started to use oil when it never did before (2 quarts in 5k miles) on average. The strange part now is that if I put in fuel system treatment it will run fine for about 2 tanks of gas. Then starts again. It has still done it occasionally with the fuel treatment just added but very seldom. I tried to use a Code Reader at O'Reillys but wouldnt read. They did have an OBDI attachment. Any ideas to whittle down the possibilities?
have the same problem?
