i posted in the discussion section. My mechanic seems to think its an injector problem. Well i brought it to dealership and they said my tps was stuck wide open, and also getting a crankshaft code, but could be due to quad running bad. It wont even crank now, but when it did, it hardly would idle, smoked black smoke, and the normal signs of the tps from the posts ive read on here. The bad thing is though was my oil was full of gas also, so it might be a number of things wrong with my quad. It went from running perfect, to me cranking it one day and it doing all kinds of crazy things. I have a sparks programmer on it.
