Does your 2000 truck have stock wheels/tires?

I forgot about that one. I had it happen to another truck i had. But it was the t-stat. The temp would get just high enough to drop the timing and just kill the power.

My 05 SS only get 13.8 mpg no matter what i do.....you should check for codes even if the light is not on.

It does have the stock wheels with 75 series tires.Can you ohms out the temp sensor to see if it is bad?I will see about get a scanner and checking for codes.

Just wanted to let everyone know what was wrong with the truck.I checked for vacuum leaks and did not find one.I checked the pvc valve and it looked brand new.No oil on it at all.I reinstall and made sure it seated.I have put around 200 miles on it this weekend and I still have a little over half of a tank.I am going to drive it all week and see what happens.It looks like that was the fix.I was only getting about 250 to 275 mile per tankfull before.
