I see you included APPS reset, you think it may help before I test the whole nine yarsd? I am thinking I will just swap out the apps and see if that works.

I t only takes 30 minutes to do the reset and no $$$$.

Not sure how apps impacts egt .... Even if throttle position is off the turbo should still spool almost same ..... Shrug

[Mopar1973Man]

The only way I know to impact EGT's is to have more drag than usual.

I agree, check this out today I was taking it to my shop, when I turn on AC and let out on clutch eng dies. Like I said it has a lugging affect. The turbo has about 80k on a rebuild and it checks out ok best I know what to check for. No end play to speak of I mean it has some play but not rubbing houseing, spins real free, spin with your finger and it spins for a little bit. Checked all boost boots, they were replaced about two maybe three years ago, there all on nice and tight.No controller on it anymore just about stock.

Reset Apps.Boost leak check.#6 manifold bolt check.Go from there.

I doubt the turbo is the cause since at idle the engine really doesn't need it... But the fact you turn on the A/C and let out the clutch and it dies is not good. I wonder how much load the A/C is putting on the engine?

[jlwelding]

I have not made time to work on it today but got to thinking AC and maybe another bearing like the fan, might be something to look into.I just hate like h--- to think my 14 month old Blue Chip vp might not like me anymore.

[jlwelding]

Ok, your not going to belive this. So I changed the filters, added two stroke (Forgot to add at fuel up) reset apps and running just fine. I still think there is a under lying problem that is not showing up.Egts back to normal, boost normal.
