I purchased a used 95 Mystique about 1-1/2 month ago and I started having some idle problems with it.
It started by the motor skipping during driving. Changed the Sparks plugs to NGK Laser and it solved the problem.
About a week after, when starting the engine in the morning, each time it started properly but just stalled after like 5 seconds. Got the fuel filter changed, but it didn't change anything. Go back to the garage and then they changed the MAF and the PCM.
After all those things, the rough idle continued and seems even worse than before. The motor has a hard time trying to stay running when I start it. On top of that, when running over 1500 RPMs, the strap starts to do a squeaking sound, even if it's brand new too.
To go to work, I have to drive downhill, and each time the engine just stall at the bottom of the hill arriving to a red light or at a stop sign. Otherwise, the idle is rough when waiting at a red light or at a stop sign and when running on reverse without pressing the gaz pedal.
I'm starting to get frustrated about this car and the money I spent to try to make it work properly... If my garage can't find the problem next time, I'll go see the dealer as I think I should have done at start.
P.S. Sorry if my language is not 100% perfect... I'm a native french speaking guy from Québec, Canada...
Thanks for your understanding!
