After doing some research, I came to the conclusion that my IAC sensor maybe messed up. I did something wrong with I was installing my FJO sensor to the ECU and things went funny. I had to change my MAP sensor and now I think my IAC sensor is bad too.

Here is why I think the IAC sensor is bad. Sometimes at idle the car would rev up and down around 1500-2000. Sometimes the idle would get stuck at around 2000 rpm until I press the throttle a couple of times before it settles down. And the problem is getting worst.

Also when I am gradually(easy on the pedal) boosting up to 7psi the car would run fine, but when I floor it, the car would get to full boost and would studder some after 30 sec. or so of boost. My fuel map seems fine. Not too lean at those boost range. I didnt have this boost problem before this idle problem started.

Do you think the IAC is the cause? What do you guys think?? I am getting really tired of the problem. I want to change the IAC sensor but want to confirm with you guys first. Any suggestion would be great.

Thanks
