The truck floods when you try to start it..unless it starts in the first couple of cranks. i have to unplug the relay, start the truck, and plug the relay back in when it does this....kinda a pain in the a** . also when you are driving downhill..foot off accelerator for a minute, then start to accelerate again it seems miss really bad.... any ideas?
