[QUOTE="RossKean, post: 1448664, member: 19880"] If injectors are dirty, RingFree or other injector cleaner MIGHT help but better to get them done by a company that specializes in cleaning fuel injectors. For a reasonable cost, they will clean the injectors ultrasonically while rapidly actuating them and pumping solvent through. They will replace the inlet filter baskets and evaluate the injectors with respect to flow and spray pattern. If one or more is off badly, you may need to replace it. Sets of used FJR injectors often come up on ebay. There can certainly be other causes but injectors are a distinct possibility. I would probably try opening up the base screw and trying the TBS again before messing with injectors. Doesn't take much time and costs nothing. [/QUOTE]
