Hello. My trail rig is a '92 XJ with a 4.0L HO. It has almost 200k and I'm looking to replace the critical sensors for added reliability on the trial. I realize that some failed sensors may result in a completely dead engine (i.e. crank position sensor), while others may only cause a rough idle. Which sensors are most critical? Also, what is the life expectancy of the main computer? Thanks.OlyJeep
