#133972, "1997 Eclipse RS rough idle and running lean....help please"
I have a 97 eclipse that has a rough idle and is running lean. My friend, who is a certified mechanic, ran a diagnostic check on his computer and found that the car is running really lean. However at higher RPM levels the motor seems to even out and run ok. We have changed many different sensors to try and remedy the problem but still cant figure it out. Here is a list of what i have changed so far.
MAP sensor Throttle position sensor EGR valve Front O2 Rear o2
The car has a header, resonator in place of Cat, and magnaflow muffler. I know I am a new member, But any help would be greatly appreciated. I have big plans for this car.
