hey guys i had this problem when i first got my truck and i had the old style super chips programmer in it...and im also having this problem with my edge juice with attitude...sometimes when i am driving warmed up engine or cold engine, not all the time but the engine seems to defuel or something. if im drivin on the highway cruisin around 55 or any speed for that matter i can push the pedal more and itll stay same rpm and seem like im not gettin more fuel put to the cylinder, doesnt make a wierd noise or anything, just stays at the same rpm same speed, nothing changes. just dont get it. or ill start my engine, no matter if its warm, hott or cold outside, and put it in drive and step on the fuel pedal it sometimes only seems to go a little past idle even when its put to the floor. it doesnt always do this either

 

Check your throttle position sensor.

 

yea that would be a good idea, but wouldnt it throw a code if that was it ?

 

Also, double check your attitude wiring... I hadsimilar issues with the wiring getting chaffed and had shorts in it... cut, soldered and taped up and no issues since. Might be a bad connection too, so try and use dielectric grease on all connections. Just a couple things to try

 

yea but it did the same thing with my old *** superchips tuner.
