ive had this 2005 suzuki df-50 for a few years now and from the time i got it, it has never seemed to idle smoothly and when starting it it will crank for maybe 5+ seconds before it hits, then it might fire up and stall, i crank it again and stays running. also when you rev it off idle it has a miss than can stall the motor occasionally. im about out of ideas and dont want to keep throwing parts at it. it runs great all the way up to full throttle.
few facts about it, the previous owner always ran crap ethanol pump gas in it. he had it since new and when i bought it, it only had about 94 hours on it. sadly ive only put about 10 hours on it over the last few years.
high pressure fuel pump seized up. i replaced it along with cleaning the scale and ethanol corrosion in the vapor separation tank. it has new ngk spark plugs.
from the time i got it it has only had non-ethanol 90 in it. it has a water separator on it.
i have good flow coming out of the high pressure fuel filter. i pulled the fuel injectors, they look perfectly clean.
when i got to start it, it cranks up to 5 seconds then will fire up and stall, then fires up and will stay running. while idling it is pretty unsmooth, you can see the motor shaking and you can hear it missing occasionally. if you rev it off an idle it will hesitate/miss then pick up or stall. once above an idle its perfect,
there is no error codes that i have found.
anyone got any tips or things to check?
