Hi All, I'm new here.
I have a 2012 XUV 550 S4 that we just got out of the shop a few week back with about 45 hours or so on it. It was in because it set for several week and would not start. The dealer said it had bad gas and the carb and was full of crud. $200 plus later it ran fine for a week. I parked it for three week and again it did not want to start but finally did. It idles and revs fine but when I put it in gear, it will pop and backfire and has no power. I have high test with STA-BIL in the gas. I can pull each plug wire and it will run and rev on 1 cylinder but will still backfire when I put it in gear. That makes me think the plugs may OK and that the problem is gas or starving for gas. Any thoughts would be most welcome.
Thanks,
George
BTW: does anyone know what size socket it takes to remove the plugs?
