Any tips how I can get it to idle without someone inside on the accelerator?

My buddy has used it on his LS1, lil better idle. This stuff is meant to clean out carbon builup. The more miles on the motor the more it will do. But why wait till theres a problem that needs adressing? The more the car smokes the more cabon buildup that was in the motor. Youc an do a couple treatments and it will stop smoking as its mostly cleaned out. I swear by this stuff and use it on all my cars. Did wonders for many older fords i owned,, my LT1s loved the stuff too. Never a problem with it. Always got a better idle out of the car after and a crisper throttle response.

Theres something ive meant to try that i heard on the impala ss website. I guess everyone used some aftermarket setup that basically does the same thing except plugs into the fuel rail and the car runs off this machine with gas and the cleaning product in it. Wel they used a vacuum gauge to know when it was all cleaned out? Seems as the carbon is cleaned of the valves they would seat better and build better vacuum in the intake? People were seeing 2-5 lbs of vacuum gained after doing these treatments. Wonder if someone took a reading, then ran a bottle through the brake booster and looked for a difference, then ran a bottle through a full tank and check again. I have a feeling we would find a gain. Showing better valve sealing - more power.

Definitely. I'd do it about every 40K miles, cleans the engine out nice
