I am still trying to get my 4cyl/auto TJ to run. It has a hard dead miss at 3000 rpm and will not rev past that point in any gear, park or neutral. Codes say MAP and O2 and I've replaced MAP sensor, coolant temp sensor, o2 sensor, cam sensor, crank sensor, new plugs. Ive checked compresson, throttle pos sensor, and run it with no exhaust with no change in the miss. Codes still say the same thing.
Heres the question. does it sound like a bad computer? Is there any way to check the computer it without replacing it. And Ive been told that the 97 has a computer that is ONLY used on a 97. Is this true?
Any other ideas would be GREATLY appreciated.
Thanks for any help in advance!
