Problem(s) dropping rpm at idle/losing power on hill
Got a problem with my truck. I have a feeling it is electrical/sensor related but not for sure.
When at idle the RPMs periodically drop from say around 700 rpm down to 500 as if it is going to stall then jump right back up.
Twice this week (yesterday evening and this morning) when climbing a hill and getting on the accelerator it will loose significant power and SES light will come on. The RPMs will climb up, but no power. Drives crappy until I stop, shut off, the SES light clears then runs fine, will climb the same hill perfectly after the error code clears. It does not happen evertime i get on it, just those 2 times. I have not been able to make it to advance auto with the SES light on to see what the code is and apparently their scanner does not see historical codes?
Recently replaced the CPS and ICP trying to trouble shoot a problem with the truck stalling. Ended up being a mis-aligned pin in the electrical connection that sits on top of the driver side valve cover right below the air intake.
The 2 symptoms maybe from different problems? I am considering taking back to the shop but thought I would throw this out there and see if any of you have input. I am thinking IPR, based on other stuff i have read but they are kind of pricey for a part to throw at the problem.
