Replacement PCM for 04 Rubicon?

[imactj2004]

I've seen lots of reference to WranglerFix.com but all of the reviews on their TJ PCM product page reference the 05-06 problem. Anyone have any luck with 04 replacements from them or anywhere else?

What’s wrong with yours?

wellll....good question.

Long story short: I replaced all four 02 sensors with recommend NTK's per this post, but I still can't get the Heater circuit test to run so I can't pass smog here in california. O2 connections are well grounded and good with power so only thing left is PCM...yes?

I'm fairly certain Mark can fix you up just call him

Yeah, spoke with him. Nice guy. Gonna go though that route.

He handles all years, 05-06 just seem to have a higher failure rate.

Mine ran better than stock with his, @John Cooper has it now, he can testify.

I sure am happy with it, not sure what it ran like before replacing it, but it's great running now!!!!

Mark is a super nice guy and is always willing to talk with you!!
