If you have a scantool, what are the intake air temp, and the coolant temp readings? I'd say you could have a bad coolant temp. sensor or a broken wire to it. If it goes, your ecm will see it as (I think) -5 deg, and will dump alot of fuel. It won't be as noticeable when the engine is cold, but as it heats up, it will become more noticeable.

11.3@123mph on 195/75/14" whitewalls. Yes, 195s!
11.2 on the big giant slicks. What's the point? Maybe I'll go back to the whitewalls. They are lighter and have less rolling resistance.
