Hello to all, maybe you can help with the problem i'm having.
My 4.0 man 5 sohc wont pass emissions, state computer says "sensors not ready". They are 02,heated 02 and cat sensors.
There is no codes or cel. Was told the pcm didn't know the engine was up to temp, so I changed the sensor for that, same thing. Another told me the engine was not running up to temp, i was running at 180. Changed the tstat to 195 degrees, now running between 195 and 200, same thing.
There is an exhaust leak on the passenger side at the joint of the manifold and the first piece of pipe. it is not a large leak, but is this enough to cause the problems I'm having.
I'm at a loss as what to do next, anybody got any ideas?
Thanks
