Put a new o2 sensor in today, also checked the plugs.What I see in the plugs makes me think its the missing o2 sensor. 2 look real lean, and 2 look real rich.
What do you think? Oh and if only two are burning rich, should I be useing so much oil???

 

O.K so I jumped my o2 wire so I have bothe plugged into the ecu now, and did seafoam flush through the vac line. Car dont smoke at all now. But of corse I now have a new problem.The car runs and drives great as long as Im on the gas. If Im on a back road driving normal (1,500-2,500 rpm) the car breaks up bad like the timming is way out, you know sputters. You can hear the tone in the exaust breaking. Now if Im driveing it hard it run great. WTF?

 

im confused are you running an obd2 or 1 setup, replace the knock sensor if it is bad, that could contribute to the rich problem, as far as the oil consumption, is it leaking? too rich for too long can cause the rings to go prematurly, check your compression
