It's not a head gasket, the compression is up on all cylinders and I have a tester that tells if exhaust gases are getting into the coolant, it tested negative. I've never really seen anything like this, and I'm a mechanic. I drove it 20 miles today and it did perfect, I went thru the drive thru at Checkers and as soon as I got back on the highway it started acting up. It wouldn't rev over about 2k RPM's and would barely pull. I got it off the road and turned it off, started it right back up and it ran fine for a few miles then did the same thing again, so I turned it off and restarted it and it ran fine again for a while. I took my code scanner with me in hopes that it would throw a code but it never did. Thanks for the advice BootlegGT, I am going to go ahead and replace the manifold gaskets tomorrow since they need to be changed anyway but I am beginning to think that the problem may be a fubared sensor, the problem will be finding out which one.
