Guys my 2010 motor is dropping and picking up RPM between 4-5k. Runs good under lower RPM. I usually pay the man but thought I'd try first. I checked the Seperator tank for debris, the VST filter was good. I just replaced it about a year ago. My plugs are not great but could be worst. I ordered new ones today along with a new gasket for the seperator tank. Should have had a new one before taking the tank off. I will admit I haven't been using any ring free. I will start though after this. Anything else I could check while I'm waiting for parts? Would it be worth trying sea foam to clean out injectors and if so how much? Or should I just stick with ring free. If this doesnt work guess I'll take it to the man.
