1.8 liter 5 speed with about 63500 miles. She was due for a good foaming. Sucked about a 3rd of the bottle in through the brake booster line and put the rest in the gas tank. This is the result after I let it sit for about 35 minutes. First drive seemed a little livelier, low rpm throttle response was instantly improved. Going to see if it improves the MPG any as well. It stumbled and stalled once trying to find idle at a stop sign when I was first leaving my neighborhood as soon as I jumped in the car after I stopped recording this video, but once I was able to rake it through the gears a few times and get the last of that shit out it hasn't had a problem since. That noise you hear at the end is my AC compressor kicking on, that was the only way I could get it to hold an idle was by to put some load against it so I could go stop the camera haha. but it's a great product, I'd recommend it to anyone who asks.
