Hey Mike, what the heck is going on with the unexpected acceleration?
Any chance of sharing the details and observations when it happens?
Hey Bryan.
It has occurred about 10 times.
Presented after the CP4 was replaced, was not noticed prior, may be coincidental timing
I have not looked at data on my reader to see what fuel rail actual and demanded pressures, VGT, boost pressure, etc. are when the issue presents.
That said, I would believe that the engine is at least at normal operating temperatures based on the amount of time/at speed I've driven immediately before it presents.
So so far, we are at an intermittent problem that occurs after engine has reached operating temperature and started after the CP4 was replaced.
After deceleration, and after light acceleration, it almost sounds like the engine is going into regen.
If I release the accelerator, RMPs drop then go to ~1300-1500, despite the accelerator being disengaged, then drop back down to normal RPMs.
I have to update the software on my reader today then I'll run DX for codes.
Any parameters you think I should look at? EGR, VGT, EGT, Boost, T/C, fuel pump commands, etc are on the list.
Thanks buddy!
I said it to you the last time we talked, and now it is even more so, I cannot wait to go back to Ram and I don't care if it needs to be a dually. I'm not brand loyal, but my last Ram was my favorite vehicle I've ever owned. It had issues too, but I just enjoyed driving that truck whether it was to the grocery store or up to Chicago from here. Just loved it. Low revving, torquey, powerful, and just rode like a dream. I hope the redesign hits soon....and I also hope they go with that 7.2L!
