Berryman Products 2630 4 Pack B-12 Chemtool Professional 3-Step Fuel System Maintenance Kit 16 oz./9 0z

I used this kit on my 06 Toyota Sienna with 92,000 miles. This product helps to stop engine knocking. I have more responsive throttle (just like 11 yrs ago). I used the throttle body cleaner while engine off, and cold. After cleaning the throttle body, I put back all air ducts and vacuum hoses and started the car. As expected, it takes a while to start the car because the throttle body and intake had a lot of cleaner chemical in it. Then I used the combustion chamber product through the brake booster hose. I started engine while the clear hose connected to the brake booster hose. After engine has stable to idle, I inserted the other end of hose to the chemical bottle. Engine started showing rough idles (as expected). I occasionally rev engine about 2500 - 3000 rpm. After a few minutes, engine had really rough idle, and check engine light blinking. ABS, VSC, and other lights turned on too. I let it run about 30 more seconds and a lot of white smoke coming out. I was nervous and took the end hose off the chemical bottle, I had about 1/4 of the bottle left. I let the engine running idle for about minute, the check engine light and other lights went out. The engine idle smoothly, but high at about 1,100 rpm. I should have reinserted the hose back to the bottle and use the remaining chemical, but I did not. I shut off engine and put brake booster hose back. Started the car again fine, rev engine couple times, to get rid of the white smoke. Engine still idle high. Next day still idle high, but after driven it about 5 miles, engine idle back to normal. I used 3M system before (on different car), but I like this Berryman better just because it has a good adapter to the brake booster hose.

I used all three cans of cleaner as directed and they worked great. It was easy to do, and it comes with an instructional DVD. I have a 2000 F150 and it seemed like it didn't have as much power as it should, poor acceleration. After using the kit I was able to spin the tires. It is hard to say if my mileage is better because it is very cold here and the truck does a lot of idling.

The instructions were simple and straight forward. The only ding I'll give it, is the enclosed DVD doesn't even have a label on it. Not a big deal, I just watched the video on YouTube and it explained exactly what to do. Too soon to tell any major improvements in the performance, but the car seems to be much more responsive and the engine used to have a small knock which is gone.

This was a relatively straightforward kit to use and came with all of the adapters necessary to clean the throttle body, intake manifold, and intake valves. I used this on my 2014 Mustang GT with 69,000 miles and it made a noticeable difference in idle quality right away. The intake valve cleaner took about 7 minutes to empty the can and did trigger a check engine light once the engine was restarted. Disconnecting the battery for 10 minutes cleared the code. Once complete, the idle seemed smoother and no longer had the occasional stumble it had before. The dealer wanted $200 to do this on my car which I declined and paid 15% of what they wanted and did it myself. Huge cost savings.

Bought the kit December 10-11. I followed the instructions and started with step 1. Seems like the step 1 air intake cleaner can was not under pressure. When I tried to spray, it dripped. The can was full of the cleaner but not the air. Tried to call berryman but they were closed.

Doesn’t list it in the description but on the box it clearly states this is not designed for diesel , direct injection , turbocharged , or rotary engines. If I would have known that I wouldn’t have bought this. Waste of money.

Worked as described. In part 2 of the process it looked like I was smoking out mosquitoes! There was dense white smoke that came from the exhaust after I revved the engine. It appeared to clean out the combustion chamber better than other products I tried (Sea Foam). I poured the third can into the gas tank for a full cleaning.

Had to mail back cause ford manufacturer dies not recommend to flush my exo boost v-6 engine, they still have not credited my account.
