I was quite pleased with the black bottle of STP fuel system cleaner, as an in place solution. Seemed to feel better at low RPM, got an average of 2.5mpg more out of it. This on a petrol car with 100,000 miles on the injectors.

Maybe you could marinade them in it?

how does this stuff work, do you just pour it in your tank? and drive like normal?

and this works well?, might give it ago, any potential downsides?

Catastrophic failure of the injectors? Ask around, see if anyone has found good results from a particular brand in your motor. Make sure there are no horror stories. I had heard good things about the black bottle of STP in alfa twin spark engines.

7 injectors?

Well its a V6 and Apparently there is one near the manifold. I found out this by browsing online while my car was away being fixed:p
Unless i have mistaken an 3VZ-FE for a 3VZ-E (Unless the multiple pages on the internet was lieing to me)

I think they may have just done the 6 regular ones though



Edit: Now that i look for it i cant seem to find anything on it. Maybe i dreamed it :o


EDit Again: I WASNT DREAMING! :D I just Missread the engine code in my rush, Its actually "some" of the newer 1MZs which have the 7th in the Intake Plenum or a kit for the 1MZ that gives it an Extra one. I must have been reading like a maniac that day :o
