[ELDORACER]

i was trying to clean out my carbon deposits from my engine because i just got my car and i heard that cold engine knock was a problem with the northstar engine. i followed the directions left in a post. i got a arosol can of top engine cleaner and i warmed up the engine to operating temp and then i put it in the pcv valve everthing was going good i then reved the engine to 2000rpms and the white smoke started comming out it was making a funny sound so i let my foot off the pedal and the engine stalled. did i do something wrong. put to much cleaner in. i hope i didnt hydrolock my engine
