Sup huys...new to the forum...but not new to the bike world...
i have this nice '06 f4i that i got 1 month ago...the bike was runing fine,until a week ago-my idle started to jump and go down, and sometimes even stahling...so i changed thr FPR and the plugs,and also charged the battery...i got some results after changing the FPR, but still the the bike runs like crap...
what do ya'll think??
thank's a lot

 

Wellthe FI light flashing and the rpms going up and down while riding points to one common problem, loose battery cable. After charging the battery and changing the FPRdoes it still do the same thing? If it only runs like crap now then I cant help you.

 

Loose bat cable. Happened to me....

 

Im like the loose battery cable patrol! lol.

 

no it's not the bat cables...checked them.
now when i roll my throttle it runs awesome....the idle is bad when i get close to 1600 rpm's,it jumps up and down~300-400 rpm's...
and no FI light...

 

sorry bob i was in the wrong post!!!
and i had a similar prob. and the FPR fixed that

 

Yea thanks moldousa..you kinda answered the guys question...
I dought that my bat. cable are loose since i just charged the bat...now my idle is good under the throttle,and it jumps when it gets to normal idle 1300-1400...
i will also try some fuel cleaner...maybe it will work!!!
