Engine Performance problem
1997 Jeep Wrangler 4 cyl Four Wheel Drive Manual 120000 miles
i have a check engine light on, code read the bank 1 running lean, but it was not running lean, I had black smoke come out of tail pipe. The mechanic has taken out the thermostat and the check engine light goes out and runs well. Its fooling the system the engine is not running at its normal operating temp, therefore calling for too much fuel! I also replaced the o2 sensors up and downstreem the cat and new fuel pump and fuel sending mech.I dont know where to turn ! Help me ! Thank you
have the same problem?
