You can use it. I just spray it directly into the throttlebody. I did not disconnect the airvalve. Didn't know you were supposed to. I've had no problems.

I think most people who use it (or seafoam, etc) put it into a vacuum line. Do a search for seafoam I think it is more popular and you'll get more hits that way.

i did 2 bottles of seafoam and what a difference it made.

just make sure you change the oil right after.

Can someone post a pic with exactly where to pour in the seafoam or top end cleaner. I poured mine in to a spray bottle and then sprayed it into the TB while it was running but I couldn't really soak the motor doing it this way. The Z is pretty clean but the intake on my Yukon is a grundgy mess. Thanks

Thanks a lot, I will be putting on a catch can soon so I might as well throw in the cleaner when I do that.

Gonna do that this week... I'm sure the GM TEC is good stuff the mercedes dealership I work at uses it for their services. They said just to get a long vacuum line and run it into the bottle? when the bottles empty let it sit for 15-30 minutes then start her up and run her till she stops smoking. Was thinking about just disconnecting the PCV there and just running a longer hose to the intake manifold port and doing it that way.

Any problems doing this on a motor with 90k? should i change the plugs afterwards?
