I tried posting this in the engine section, but noone responded. Anyways, has anyone used it? My 4.9 has 125K on it, so I thought Id try some. They have both a liquid and aerosol kind, which is better? Also, any procedure recommendations? Lastly, what can I expect after I do this?

I think Id use the liquid, as you just pour it into a vacuum hose...... But, if the car runs OK with the air intake hose off, then id use the aerosol, as it will clean the TB some too.... its your call.... Do some experimenting.....

Ive used it, and Id use it again.....

To do it, do as the directions say, and have someone in the car to keep the engine speed up.... Let it sit after your done (10-20mins) and then give it MANY WOT runs to really blow it all out of there.....

I think my car ran slighy smoother, especially at idle.....

Just so you know, its gonna smoke like the devil for a while..... Its gonna look like you lit it on fire..... normal...
