Test run complete. It did fine (except for one thing) all the way up until we decided to try to go down a spot we shouldn't have. As soon as we decided to back out of it the jeep started pouring smoke out the exhaust and motor. Seemed to possibly a head gasket going. But then it seemed to smell like fuel and it quit blowing smoke. Then it would only do it when I got on it hard or rev'd the motor up. Here are the issues. It is idling around 1000-1200 rpm. When I let off the throttle the rpm's drop extremely slowly. then there is the smoke issue. Seems to be running ok otherwise. Wondering if there is an exhaust leak I can't hear or see before the o2 sensor and it's causing it to over fuel. Now when I impede the hose going from the airbox to the valve cover it drops rpm's to around 600-700 (normal) and sounds like it is still running fine.
