I posted in the past about the problem I'm having, however it was a while. Please don't blast me for posting again.
Problem: Sometimes I get stuttering between 1500 and 2500 RPMs. It occurs while pressing the accelerator, if I let off the throttle, it goes away. Also, if I apply more gas, it seems to go away. The issue doesn't seem to be as present when not in OD.
What I've done: Replaced plugs, wires and fuel filter. Cleaned TB, however I was unable to get the IAC out.
The issue was less noticeable after the TB clean, but is still there.
