truck wont idle in gear Well i thought i fixed the problem changing the MAF an it did, but i was sick for like 2 days this week came out to start my truck an it had a dead battery well gatta jump an know its back to doing the same ****. Its bad if im going like 30 an let off the gass completely it dies, its been fine sense thanksgiving an now this.

 

If the tune is way off, especially at idle, when you loose power to the PCM its adaptive idle learning info is lost and it will run like crap till it re-learns idle.

Drive it for a bit and see if it improves.

 

My tune was great. At idle sometimes then engine light would blink then turn off once i got going. Lets hope it relearns idle, other wise going back to the tuner asap

 

A blinking check engine indicates missfire is happening so it may be something mechanical.

 

Thats what ive herd bout the misfire. Ima go to Pavlock as soon as i get the time an seen what up with my corrupt black beast
