I have a problem with my 90 model and I am looking for ideas. The jeep starts fine but has a dead spot around 1000 to 1350rpm. It will rev past the dead spot but as soon as it idles down it will die. It will refire just fine and idle after that. It has also started to idle rough after about 5 minutes of run time. I have checked the common renix grounds. It has a new fuel pump, filter, pressure regulator, O2 sensor, and recent plugs and wires. I have checked the fuel pressure and it reads fine. On a diagnostic scan the only thing that checked bad was the O2 sensor which I replaced and it still didnt fix the problem. Any ideas are greatly appreciated. I have been looking around at the site for a long time, just never registered until now.
