One of sensors is failing, maybe the O2 sensor(s).
95 eclipse has a low idle
maybe a vacuum leak
How high is your idle? idle should be 800rpm good oil pressure is obtained at this idle
Vacuum leek
Is it a constant high idle? First place to look is the throttle wire connecting to the throttle body. It should be tight, but not pulling the throttle plates out of alignment. also might want to consider the grade of fuel you're using (sometimes a fuel system cleaner additive can help).
My car has run perfect until I replaced the battery.Now has idle issue. My idle at times is low. 600 - 400 rpm. Cold starts are good and the first 10 min seem normal, but when warm I have idle issue on my GT Eclipse. Idle Sensor? Reset Idle code? Any other ideas?
a vacuum leak can cause high idle
normally idle around 1000rpm
I think your alternator doesn't work properly.
High idle, misfire, check engine light,High idle, misfire, check engine light,
Idle is computer controlled and can NOT be adjusted.
You can adjust the idle.
