So I posted a week ago about my 03 5.7 stalling and running really rough a new bell crank sensor complete throttle body cleaning and new gasket an fuel pump later , dealership still has truck saying it's still running rough and cuts off! The tech said they checked battery terminals and they look good. What else could it possibly be!!

 

Valve springs?

 

Or PCM

 

check ALL strap grounds.. especially the PCM... look for loose or corroded harnesses into the PCM..

check coil.. matter of fact, replace it..

this is something that is difficult to isolate not being with the truck..

 

Hemis have 8 coil-packs. One for each cylinder, so replacing them *****-nilly is a long shot.
Is the stealership coming up with any codes?
You would think they would be able to diagnose the issue by now.
A code would at least let you know if a cylinder was misfiring and then
you can swap out coil packs for the bad cylinder.

 

They've had it a week?! Scares me when the dealer just throws parts (and your money) at the problem. Bet when the new fuel pump didn't fix it, they didn't put the old one back in... I don't see mention of plugs or plug wires. How many miles? They checked the battery terminals, hunh? Smart thing to do while spending $800 or so of your money.

I'd want to see what codes it's throwing.

 

It's an 03 5.7 with 58,000 miles. It only threw one code p0132 which didn't show up until after the second time I brought it BACK to the dealer. The tech said it's because of the fuel pump which I said doesn't make any sence just fix it! They "said" they checked the terminals I'll ask them again tomorrow and no the fuel pump didn't fix anything it'd under warranty so I'm lucky there and the gave me a rental car for the time they have my truck. What's funny is my truck was running so good I was about to buy a super chip and BAM, this crap. I have only been a dodge owner for two years and don't want this to put a bad taste in my mouth because up until now it has been great. They also said once they replace one part the truck throws a different code, when I asked which ones they said the tech that was working on my truck left for the day ( of course) I have hit my limit of being patient and I think I'm going to make a surprise visit tomorrow!! Thanks for all the feedback.

 

From OBD-Codes:
"A code P0132 may mean that one or more of the following has happened:

The oxygen sensor heater circuit is shorted out
The wiring to the sensor is broken / frayed (less likely)"

 

DOH!!!! Sometimes I just plain don't make the mental leap from my engine to the hemi's... and that is/was the case here..

 

They are replacing the computer as we speak! I hope they are bright enough to see if any of the connections are bad.
