I have a 2008 Denali truck with a 6.2 and the throttle body blade got opened during a cleaning and the truck now has a high rpm at cruiz causing it to drive itself and downshift funny in deceleration I've tried all the relearn procedures I could find still no dice. Any ideas??

TIA

 

There is a recall on the TPS sensor on the 08- up trucks/SUV , you might need one

 

I had to use a good scanner to do the relearn on mine after i did a cleaning. Like a tech2 or a solis.

 

Ok thanks guys. We have a high dollar snap on boy sure if it will do the relearn or not. I'll find out thanks. Another question does anybody do custom tunning on these trucks via sending the ecu to them? The truck has vvt delete and few other mods. Thanks

 

HP Tuners scanner will do the TB Clean reset.

 

Used the snap in scan tool and did the relearn took all of 5 seconds and it runs great!! I'm still needing some tuning on the truck it's a little rich at a idle. I have a spare ecu does anybody do mail order ecu tunes anymore? Or email tunes that I can use efi live to install?
