Hello, first off let me begin by saying thank you to Moses for your site. It has helped me fix a lot of issues with my jeep.
I have a 1988 jeep yj with the renix 2.5 tbi setup. The problem is that the jeep starts and runs but consistently spit, sputters and stalls. I can be driving down the road doing 55 mph and then it is like somebody turns the key off and back on again. it does this at idle as well.
Things I have already done/replaced: new cap, rotor, plugs, wires, coil, ign. Module, ign. Switch, and the cps.
I have gone through and tested the coolant temp sensor (for the ecu), intake temp sensor, map sensor. Also pulled the wiring harness from the engine compartment and went through each individual wire with my multimeter to ensure that they were good. I did this under the dash as well and cleaned all grounds. The throttle body i rebuilt about 6k miles ago. New fuel filter and pump.
I am at a loss at this point and i hope for some guidance. The only thing i can think of is the ecm is going out but not positive.
Thank you for your help, and i look forward to your reply
Thomas
