before anyone says anything i have searched and havn't found what i'm looking for.
I just recently installed the MD 5/16 spacer and the idle is low around 700 compared to my idle before i had the spacer which was 1200. the idle is smooth not rough or choppy and is a constant idle of around 700.

Is this normal??

 

anyone?

 

My idle has always been around 700 rpm, certainly nowhere near 1200 rpm. you must have had a vacuum leak somewhere. Try the ECU/drive by wire reset procedure, and then check for vac leak.

 

700 is the spec tolerance range for idle.

1100 RPM is only for warm up.
