    Running kind of rough(maybe)

    This is the first 8 cylinder I have owned in 8 years(1998 LS1 Camaro). When I rev up the motor above 1500 RPM in neutral the car feels kind of like it is miss firing, but not. It might be motor/transmission mounts. . . . Maybe. Or is it just suppose to run like this?

    well congrats on the car, i would check the pcm library for stored or pending codes for a misfire if nothing comes up then the trans mount would be the first culprate, how many miled do you have on the car!

    also try cleaning the maf, there is a cleaner sold at your local parts store or if you have some brake cleaner laying around give it some juice and see what happens

    The car has under 70k. I will give a bit more time then check for codes(I just had my PCM flashed).
