1997 Mazda Protege 4 cyl Automatic 154000 miles
ok now I have a problem thats has been happening the past few days.
my car rpm is bouncing up and down. The car is stuttering when at idle. It goes up to its normal 750 rpm then goes down to 200 rpm then back up to 750 rpm. Its even worst if I turn my a/c on. There are times the car does turn off.
i later tried throttle body cleaner in the throttle body/intake manifold and the idle was not rough and the rpm when up but when I took it for a test drive again later that same day it started running bad again.
i was also wondering if the bad idle can be caused by the maf sensor
there is also no check engine light
have the same problem?
