I'm planning to take my wife's minivan to the dealer for their Motorvac Fuel System Cleaning process. Is anybody familiar with Motorvac process and products? Is it worth it?

Well, I have tried lots of things already... Syntec Fuel System Cleaner, Techron, Redline SL-1, BG44K... It seems the problem is the intake manifold. I'm not sure what caused it, but the intake manifold used to be covered with a black goo inside, probably by-product of the combustion or oil evaporation. The minivan, a Villager with the 3.0L "VG" engine, started having start-up problems. After reading some internet groups, it seems this is very common in this Nissan engine, even in some of their 4-bangers. So I attempted cleaning it myself using Valvoline Synpower Throttle Body cleaner. It did a pretty good job and the staring problems are gone, but there is still a engine miss at idle which I haven't been able to get rid of in addition to a "looping" idle when cold. I'm hoping this professional approach can reach those places in the intake manifold I couldn't reach with the TB cleaner. I'm planning to also re-adjust the engine idle and the ignition timing, which are the other two things I haven't tried yet. Thanks for the suggestion anyways.quote:

With the right chemicals, this should work. But for my money I would run a bottle of Techron first. I'd give you a 90% probability of doing the same with a $6.00 bottle as I have done 100's of times for people.
I've only heard good things about the Motorvac cleaning process. It works better than gas additives because the concentrated cleaners are pumped into the fuel line and injectors. Because you need some special equipment, it's done by shops and not by garage mechanics.quote:

Is shooting an spray down past the throttle body a better idea. I worry about a fire doing it that way.
