I've been having an issue with my 1990 limited for the past 2 months now after driving it for over a year mostly problem free. When I first start it, it runs terribly. It almost feels as though a cylinder isn't firing.
However, once I have been at operating temp for 5 to 10 mins of driving the problem completely goes away. I tested the Intake manifold temp sensor as well as the coolant temp sensor and they're both working the way they are supposed to. Plug and wires are new as well.
I am at a loss at this point, I can think of reasons why it would run badly, but not many reasons why the problem would go away after the jeep is warm. Is there a sensor that is used during closed loop that drops out in open loop? Any help would be greatly appreciated. Thanks
