I have a 1999 Ultra with the M&M fuel injection & it is flooding out all the time & runs poorly. Last year I replaced the injectors, engine temp sensor & adjusted my TPS & got it running ok, drop in fuel mileage down to 30-40 from 45-50. I had bought a Baro sensor & intake air temp sensor but had not put them on until it acted up this year. Seems when it turns cold out, it runs poorly, missing & popping. I put the baro sensor & the intake air temp sensor in it & then got a TPS since when it wouldn't start I messed with the TPS & I could at least get it running. But no matter where I put the TPS (it will set the light if I go too far either direction) it runs poorly. I pull the spark plugs & they are wet, so I dry them off & dry out the cylinders & it runs ok for about a minute (maybe less) & when I recheck, the plugs are wet again. I also replaced the fuel filter & the hoses inside are in great shape. I got some new SE 10mm spark plug wires & put them on since in the 30000 miles that I have owned the bike they have never been changed. Plugs have been changed also. I don't mind replacing some of the sensors since it has 83000 miles on it & it is a 1999. But aside from the computer, all the sensors that control fuel have been changed, with no difference. I did get a crank sensor but that should not affect fuel & I did pull the old one out & it looks ok. In a car if the crank sensor was bad it won't start, I would think that on a bike it would work the same. Any help would be appreciated.
