I have an 03 Hemi 1500. I installed Edelbrock headers, Magnaflow cat, and flowmaster single 3" into 2.5" duals. I also installed new O2 sensors. I am recieving a P0132 code and the engine stumbles sometimes. I don't know if the computer is still getting used to the new set up or what. Any advice would help.

 

Could be. Did you reset the computer when you installed the system? You could also have gotten a bad new O2 sensor. I would recheck the connector and make sure no pins are bent.

 

yeah I reset the computer but no help. this is my second o2 also.
by the way, nice bighorn.

 

Is the Magnaflow a high flow cat? If so, you may have everything setup correctly and still get a CEL from the rearward 02 sensors as the air passing by is probably out of spec. A PCM reset may help, may not, worth a try. The stumbling engine is the PCM trying to adjust the A/F ration based on the information it's getting, which is no probably incorrect.
If not, do the non-fouler trick that you would do if you had cut out the cats. Should work for you too. I just told someone else about it in another thread.
I did a "DIY" on it a while ago, search for my "how to" in the "DIY" section, it's a simple, $10 and 1 hour fix...

 

Yeah, its a high flow. Think I'll research that fouler trick though. Thanks for the help.

 

+1 on the nonfouler, did it to my durango , worked like a charm

 

I found out through searching the past threads that the Bosch O2 sensors do not work. Put in one from the dealer and presto. Thanks for the help guys.

 

Good deal! I knew that search feature was good for sumthin'...


Hey, dirtydog: I think you need to say something to this guy. He used the Search Button!!!!!!!!

 

Thank you Captain Obvious.

 

Inside joke, the 'dog has a pet peeve about people not using the search feature and to be honest, you are maybe only the second person that has posted where he's used the search to try and solve a problem in the last month or so.

BTW: My bad, I know damn well that Bosch's don't work, when your post said you replaced everything including O2 sensors, I should have asked & saved you some time. But when I saw "high flow cats", my only thought was using the non-fouler trick...
