How is the performance of your 16vlv. Does it feel as if it is struggling to pull in the higher RPM range? Say like 4,000 on up?
My car has the exact same issue with it. I replaced the airflow meter w/ a known good one, but I still have that same problem. My car will not decrease idle from 3k, then all of the sudden it will drop back down to 900-1000 rpm.
My car feels like it is experiencing a lack of power. It in no way feels like a 16vlv should. When in 3d - 5th the car no longer wants to pull up through 6700rpm. She is acting like a dog.....!
