Atv had been running poorly for a long time running very rich black smoke out of exhaust, hard to start spark plug fouling all the time. Long story short I found that the dealer did not hook up the hose to the temperature pressure sensor when they had it in for some other service. After I hooked up the hose it runs great.. However now the indicator light is constantly flashing, no pattern no break it just flashes. When you first start it thr indicator is not on, it starts flashing after 5min or so. I replaced the spark plug, O2 sensor, Temperature pressure sensor and the injector (it was leaking). Like I said it runs great just that stupid light. Might just put tape over it and call it good
