Berryman Products 2640 4-Step Professional Air & Fuel System Maintenance Kit,

Full on tune up in a box. Powerful PEA detergent fuel system cleaner, intuitive and easy to use intake fogger - with all the fittings and hoses necessary to perform the cleaning in several ways, along with the can being designed to spray in any orientation without loosing propellant and wasting a huge portion of the actual chemical. High quality MAF cleaner, and throttle cleaner, which are NOT the same and should not be treated interchangeably. Easy to use instructions for those not as mechanically inclined. Might actually be able to avoid a walnut blasting on the intake valves on my direct injected car, as the intake fogger was so strong I could audibly hear carbon being loosed from the valve, and scope view inside the engine proves my experience. Additionally, the fuel system cleaner contains a hefty amount of PEA, which is the main active detergent in fuel cleaner additives that does the bulk of the work, most other chemicals are only supplementary, lubricity additives, or useless.

I used it on my 2013 Volvo S60 T5. After this treatment my engine stopped burning oil. I'm going to perform this cleaning every 2 years on cars that are 10+ yrs old.

Works great! Made my old van run like new! The van had a rough idle and the service engine light would blink if the car sat at a red light for too long. I was getting codes for 'random misfire' and 'cylinder 6 misfire'. These vans do have a lot of trouble with head haskets and intake gaskets, but the intake gasket was done about a year ago and the entire engine was replaced in 2015. The van had needed a new idle speed control motor and when I replaced it I noticed that the pintle was severely coked up. I knew that an upper intake and throttle body cleaning was due. The van had belonged to an elderly couple before I purchased it in 2017 and I am guessing it took a lot of short trips and was not warmed up all the way often enough. After purchasing the kit I followed all the directions to treat the engine. I did do one thing differently. For step 2 I ran the cleaner through the throttle body, but I also removed the idle speed control motor and ran the cleaner through that passage as well. That might be helpful if you know that the idle passage is coked up. Anyhow the van runs very well now, has much better acceleration, and idles smoothe as butter. After driving the van for about 30 minutes the check engine light went out and all is well.

I'll have to give this a good review, I've used this for my 96 Tacoma. I've had the truck since early 2000, and I've not necessarily been kind to it. Used this product per the instructions, by the third step, I could hear a difference in the idle. After finishing up the kit, I did need to reset the check engine light, (mass air flow) not a big deal. Anybody who has a Toyota knows they are picky on the MAF sensor. But it was idling higher than before, had to back the idle off by 500 to 600 rpm. Didn't realize I'd adjusted it that much over the years. So I'd think that just that alone would regain enough fuel mileage to pay for its self in no time. I live in the mountains of western North Carolina, a lot of steep grades to pull,, and with over 256,853 miles on the engine I'm excited to really get out and see what the long term results will be.

System worked great other than Sensor cleaner (step 1). The straw would but mate with the cleaner can. Ether the straw is to big or nozzle hole is to small. I used without.
