HILLBILLY DELUXE!!!
When my truck starts and is idling cold, you can hit the throttle and it wont stumble, but once it warms up, it stumbles like an irish guy on st patty's day. itll bog down then itll rev like normal. i replaced the TPS (60 fvcking dollars later) as i needed it and it helped a little, but it still stumbles. we've narrowed it down to either the IAC or Coolant temp sensor. i read that it could be the EGR fvcked up and stays open or doesnt open enough but when we did the heads we cleaned the egr ports on the heads and intake. i wouldnt think its the egr cause that wouldnt cause idle or throttle problems. youd think.. any help if someones had this problem would be great! thanls
