Hi, I have the above mentioned 2003 Sportster 4TEC which was no end of frustration last summer. When we stored it for the winter after summer 2013, she was running great. We ran the gas tank dry, made sure it had antifreeze and put it on the trailer as we do every year. Last spring we filled it with gas checked the oil and coolant and dropped it in the lake. She ran like crap. No bottom end, no top end, stumbled just awful. We added fuel additives, but no change. We pulled the boat, checked the fuel filter, clean. Checked the fuel pressure, dead on, checked the coil packs, all good, pulled each injector, pretty patterns and changed the spark plugs. We even did a compression test on each cylinder and while one was alittle soft it was not out of range. I am pretty sure the engine is running rich, it burned a lot of fuel, and smelled "sweet". Myself and my mechanic can not find a way to lean it out, if that is the problem. Do the injectors need replacement? I know it is not going to run nice this year with out help. Please help! Thank you,
Howard
