no mileage and rich

How do you know the O2 sensor is good?

Have you checked the ECT sensor with an ohm meter? A faulty ECT sensor will cause a horribly rich condition.

Just because a sensor is not throwing a code doesn't mean its not faulty.

What is your base ignition timing set to?

well i checked my timing and it was off from a faulty tps but now i just ran a compression test and every cyl is over 155psi but no.2 is at 81 psi so head is coming off and also my coolant is always to high on pressure so i think that the head gasket is cracked at a coolant jacket, the coolant wasn't just a hot coolant smell, but with a possible fuel smell from exhaust
