OK.......here's what's going on with my car.
My car runs rough, hesitates, sputters, and feels as if there is a mis-spark. So, I install a new cap/rotor, new plug wires and nothing happens. So I then install both a new Temp Sensor and Temp sending unit. Still nothing happens. So, I then unplug my Pro-M mass air meter while the car is running and nothing happens. So then I think I have found my problem. I then buy a new C&L mass air meter and install it. I then run codes and the codes come up with the Idle Air Control and the O2 Sensors. So, I change out the Idle Air Control which is located on the passenger side of the car near the fuel rail (please let meknow if I changed out the right one). So I am wondering if I need to change out the one on the Throttle Body? Also, the O2 Sensors are not that old. But maybe I do need to change those out again? So with the help of a local mechanic, I found out that the O2 sensor on the driver side is running lean and the passenger side is running fine. I do have an adjustable fuel pressure regulator installed as well. So, after installing those new parts, my car now idles better. That is it. I forgot to mention that when the vehicle reaches normal operating tempature, the check engine light comes on and the problem gets worse!
