anybody know if a motor built for boost with low compression pistons in will idle low or could it be my cel. throw a atmopheric pressure sensor code. i also think i need it retuned cause the turbo has been on about a year an half. b16 motor incase you need to know

It might help to let us know what the idle is.

and the year and model of the car.

the CEL could be causing the low idle.

idles like around 300-700 it just seems very low to me it could be the cel or lower compression pistons or needs a new tune. hard to tell.

low compression isnt going to cause a low idle.

fix the obvious first (CEL) and get it tuned. if everything is fine the tuner can adjust the target idle with the program he uses.
