I'm of the opinion you can't "clean" the fuel injection.
If the problem is with the fuel injection, then something is broken.
If it's broken, it has to be replaced.
A fuel injection cleaning done by a shop is simply a can of tiger pizz into the fuel tank with a 1000% markup.
So, IF it's the F.I. (and only if) it's replacement time for the injectors...




Do your due diligence with your basics first before you jump to conclusions.
