07 5.4L Misfire Problem

[cmfish]

Dropped it off at the other dealership where my friend knows the service manager. Spoke to him and he told me about the warranty on the cats and said he will try the least expensive routes first. Going to try reprog the comp first, then cats, then plugs... Hopefully I'm not out of my truck for too long, although I have heard the cats are back ordered. Might have to bring my Jeep back to daily service for a little while. Thanks for all the comments!!

Ok I have had similar issue for a while. Under heavy acceleration the truck acts as if it is missing. Had a missfire code once for the #6 changed the COP to no luck. I have asked several mechanics what could be the problem, none are sure but want to change the plugs for me. Now I get a F0430 cade and it says could be converter, etc. I am at 80032 what should I try first? How do you test a converter?

mw3538... Don't hijack threads; start a new thread with your question and you'll get better advice. Also give everyone more information about your truck such as what size engine, how many miles, service history, etc. Also do a search for your code and testing a converter and you'll find lots of info.
