I removed the throttle cutout last year so i know that's not the problem. It acts like it is not getting enough fuel. It will bogg like a cold carbed motor. It does it even when it's warmed up. Then all at once it will take off but then if I stop again it will just bogg again. I also put new plugs in it and pulled the electric fuel pump out and checked the screens on the bottom and they were fine also. Could the pupm be bad or an injector? It used to just do it when it was cold but now it does it all the time. Fuel injected shouldn't be that way should it?
