I have a 1997 XJ having some wiring issues where the three connections meet up with the ecu by the airbox. After trouble shooting why it was stalling, i replaced the CPS which did not fix the problem. I seen a post about bad connections at the ecu. i cleaned the connections and used dielectric grease to try and fix the problems. It definatly helped but i can still slightly bump or wiggle the ecu/wiring and make my jeep stall and have light/turnsignal issues. I wanna fix this!!! i need suggestions what can i do

Change the ECU?
Change the Wiring Harness?
Sell it im wasting my time?
this is an easy fix?


This Jeep is a 1997 XJ with the 4.0 6 cyl completly stock engine

 

Bump

 

Have actually determined where the loose connection is?? Could be a loose pin in a connector. Find the loose connection and fix it. Or start replacing things till the issue goes away.

 

Bump it's still having issues but not as bad I took it wheeling today and only had it cut out twice

 

so you have it down to a loose connection at the ecu?

 

I can create this issue by grabbing the harness at the ecu and it will cause my head lights to go out or wacky and make it cut out idle funny

 

Should I test my battery load ? It starts and runs around fine. Also it goes into gear really hard really really hard !

 

i would say, if you grab the harness and a wire is loose and your jeep dies. its that. that is yourr problem. fix whatever is loose.

 

^yup its in the ecu plug
