My ECM has become unreliable and after research found out it was crap and only used a couple of years. I was told my the Jeep junkyard that I could swap in a 1991 intake, harness and ECM to fix the problem. Has anyone done this before? I'm not looking to swap in another bigger engine at the moment. This jeep will be driven by my son in the desert. Thank you.
