Re: Cleaning Fuel Injectors.

There is a product available from BG called 44k that is a fuel tank
additive that *really* works. I have fixed many a hesitation and
emmissions fluctuations on customer's cars. The only drawback is it is not
available over the counter. You will have to find a garage or service
center to sell it to you. It runs about US$15-20 a can.
