Re: Fuel injector cleaning
marren flow tested mine before and after cleaning then gave me a printout of the results. they also ohm tested `em and looked at the spray (not sure how they do that... dye and blacklight??) and put on new orings. 2 of mine were pretty fukd and the others were not great either. of course i have a somewhat low mileage sy (57K). the guy that had it before me let it sit for 5 years................ without starting it.
