OK so I noticed this only after I had my engine parts powder coated.... which entitles me taking apart the intake manifold and vaccum lines. Now I labeld everything to insure it all wen't back to normal... The car runs fine and great vaccum pressure is noraml when at idle I also sprayed around the engine to make sure there was no leaks and it's good, BUT I have now noticed that if I put the pedal to the floor and bring it up to about 5000 rpm and then put the clutch in it will sit at about 2000 RPM. It will sit there till I tap the accelerator pedal again and it will drop to normal.
I have cleaned the throttle body out, loosend the cable even more, made sure there was no air in the coolant lines, and just can't figure out what the deal is!
Although I did notice that if I am cruising on the highway and my RPM is around 5000 and I come off the highway it won't sit at 2000 it will go to normal!
Anyone have any ideas?? or had the same problem?
