John/Horace Posted July 29, 2021 Report Share Posted July 29, 2021 Throwing parts at it getting expensive and not working. Write down what has been done and bring to a recommended tec with your list. I bought a used Jeep that had rich condition and O2 sensors changed more than once. Signal from upstream sensor was not getting to ECM computer. Two feet of wire harness replaced. ECM had 60 pins and one of them wasn't getting a 1 volt signal. No melted wires or obvious signs of problem. Some issues can be tricky to nail down . jkeaton, 2late4u and Armando G 3 Quote Link to comment Share on other sites More sharing options...

I would have the catalidic converter checked for blockage. 2late4u 1 Quote Link to comment Share on other sites More sharing options...

Not the cadilitic converter, issue wouldn't change from running fine to getting in and not running fine. Crank sensor took a crap. Quote Link to comment Share on other sites More sharing options...
