just finished radix install, in park when i rev it a little like 2500 and let off truck and revs drop it will stall or almost stall.
any ideas. it also stalled once when i came to a stop at an intersection

also what is covered hose barb on j-tube for

any help is great thanks

 

Mine didn't like to idle very well when I first had it tuned, it would idle up then down almost stall every once in a while. Had to have the idle turned up a bit when in park. Don't know if that's the same problem.... but that's what fixed mine.

Not sure about what the other barb is for I left mine as it was with the plug/cap on it.

have you cleaned your thorttle body lately

 

truck only has 25000 kms (16000miles) on it tb is clean as a whistle

 

Mine kinda idles funny when its cold, but once it warms up idles like normal. Did you install the factory tune that came with it, or get an aftermarket tune? Or neither?

 

I cut and pasted this into your thread for you.

2003 is DBW and is non adjustable at the TB. I am not sure who you spoke too at magnuson, but they need to get their information correct.

I would be checking for things such as a vacuum leak, Fuel Pressure, so on and so forth. Do you have a Fuel pressure gauge? can you tell me what the fuel pressure is at KOEO?
