ok guys i just changed the plugs and it revs wayyy better

but now when you sudenly gas it ,it has a vacuum sound like a whistle similar to the tbs sound., i sprayed all the hoses with carb cleaner to see if i could find the leak but no luck..

my next guess is that the IM broke somewhere.. any ideas guys?? any one with similar problems?



ONCE I GET MORE INFO ILL POST IT.. THANKS GUYS..

Maybe try using propane. If there is a leak your RPMs will go up. Might work better than carb cleaner.

I checked out an Electronic Stethoscope last week, from Cornwall Tools. It only heard the strange noises (Vacuum Leaks etc), all the normal engine and ambient noises were masked totally. Amazingly effective tool, for about $400 though!
