For the last couple days, I've noticed my car has been running hotter and feels like its really lean. Almost like its running out of gas but not quite out. Sometimes, like at the track tonight, It completely cut out on the line. Then picked back up but was really slugish and got exteremly hot on that particular run. Like 220.
Does anyone have any Idea what this is?

Its throwing no codes, the fans are fine, thermo's new, water pump's new, and no water in oil.

 

anyone?

 

Have you verified good fuel pressure at both high/low vacuum to fuel regulator . Also Have fan's been reprogrammed or manually switched, otherwise 220 is normal when not moving for a while..
