Hello guys I have a 04 Auto 8, with about 51,000 miles. Lately i have been having problems with my idel. Ever time i put it in "N" or in "P" it goes up and down on its own, it seems like its sucking air from somewhere dont know what to do. I was told that it might be the spark plugs????????? Any suggestions!!!!!!!!!!!!!

so far i have a K&N intake and and trottle body spacer, dont know if that is the reason, anybody outhere with the same problem??????

 

Is it your AC on?

 

no my a/c is not on. i was also told that it might be the Maf sensor. they told me to clean, but how do i clean and with what..

 

get rid of the throttle body spacer. when did you last change your plugs?

 

So it's the spacer. Going to change my spark plugs this weeakend..should I change my wires too?????
