ok here it goes my 1500 ram with the hemi is not doing so good right now.. It has thrown the check engine light and i got the codes PO175 and PO172 ( both banks running to rich) ok so when i drive it which right now i dont cuz i have to two foot it at all times or it dies at the light, when it down shifts from 3rd to 2nd and 2nd to 1st the lightning bolt light flashes on the dash.. Can anyone help me on where to start i have heard about the Electronic Throttle Control , but i dont think thats something i can do i was told the dealer has to do this anyone know about the warranty of that or a ball park figure of how much its gonna cost.. thanks for your time and ANY help will help tremendously.. Thanks Again

 

This might be kinda stupid to say ,but have u checked your air filter lately ?
If your filter were clogged w/ enuff dirt or in some cases mud.
My buddies do a lot of muddin and the first thing they do when they're done they change to a clean filter.

 

yea man i changed that when it first started this and i replaced all the plugs, compression is good, all coils are firing, and all the injectors are sprayin, im lost

 

Here's another idea . It's my last one too.
What about the mass air flow sensor?

 

well it was a good thought and i tried these motors are speed density so im lost man if you know anyone that might be able to help me they can email me or ask on here here is my email Stangman2305@yahoo.com thanks

 

correct me if i am wrong, but aren't these normal symptoms of an oxygen sensor going bad; running too rich and like ****.

 

well thats what i thought, but i thought the codes would tell me that but maybe i should just replace them and see

 

Ok, the codes pulled simply state that the banks are running too rich----duh!!! I would definitely change the O2 sensor. You may also want to put a scanner on it just to make sure no other codes have been lit.
If the O2 doesn't take care of it, it's time for the shop. Just for giggles and grins, make sure you haven't sucked anything like a rag or something into the throttle body or the connecting hose from the filter to the TB.

 

well i have taken the air intake apart and nothing was in there.. so its not that, but as puttin in on the scanner i just wanted to try to stay away from the dealer cuz we all know they like to screw you a new one when you let them look at it but i guess i have to bite the bullet and do it im gonna change the 02's and see what that does..

 

I just had trouble with my 04 Hemi pickup, similar symptoms i think, it started running real rough an would die whenever you took your foot of the gas an it dropped to idle, then you would have to give it gas to start it and couldnt let it drop to idle rpms. I read in a couple forums about broken valve springs an told the dealership bout it. Mine wasn't showin any codes and after two days of being lost they called back and said i've got a broken valve spring. So that may be something to check also.
