while doing the GM top end cleaner...
-the car has to be on.
-you should hold the throttle open to about 800-1,000 RPMS.
-empty the entire bottle.
-after you empty the bottle turn the car off and --let it sit for 15 minutes.
-after all that it says to turn the car over and let it idle (I plan on beating the crap out of mine)
I also plan on getting the oil changed after I'm finished.
