So ive been having idel problems, and i just changed all my plugs and that took away my hesatation problem and solved my idel problem so i was happy. then i went to work, got off and on the way home i let the car get up to temp and boosted it a lil. and the very next light it did the whole wanting to die thing. i really dont get this it idel's perfect when cold but when it gets up to temp it goes to ****...please any advise?

 

it idles perfct when cold...just when it starts getting hott it goes to ****. maybe it could be simple as replacing o2 sensor. i have a DP, custom cat back, intake, FCD, MCB, afr and boost gauges. oh and when it does this idle thing the AFR goes to ****, like it will be at rich then jump all the way to lean then back again..

 

could bad motor mounts give me bad idle? becuase ive noticed my motor rocking like a carnival ride.

 

Standard idle problems. Adjust the TPS, find and fix all vacuum leaks (this is the most likely cause). O2 sensor has nothing to do with it.
