Motorvac questions
Anyone on this board ever try this on their expy? He says that the price is about $100 and they mix 4 gallons of your fuel with an additive and they run your engine for about an hour. He claims that it helped with the rough idle (he's cleaned his MAF) and the ummph from the engine is back whereas it was sluggish beforehand.
Any input/thoughts is greatly appreciated.
Drive safe,
Dan
