f4i strange issue
I have a 2002 f4i, about 20k miles on it. Only mod is MIcron exhaust. While I'm unsure if the previous owner abused it, I know I do not. I started to get the infamous CCT buzzing so I replaced the tensioner and the bike was running a little rough afterwards. After reinspection I notice I left a vacuum hose off the left side of my airbox. Put the bike back together and everything felt great for about 100 miles or so. Now the bike is slow to accelerate. No real hesitation or bog, just slow rpm climbing, also the FI light has come on since, It is flashing 8 times which I understand is the TP sensor. If I unplug mine with the bike running no change occurs. I would expect the idle to dip or raise since the computer isn't reading throttle position any longer. I am wrong to assume this?
Furthermore being that I am a college student funds are bit low, I am willing to buy a used set of throttle bodies online to replace the sensor, but is this geneally a bad idea?
Sorry for the long post but the last 6,000 miles this years has been nothing but a dream coming from a ninja 650r to the f4i. However, I am losing hope in winning this battle, because I honestly don't know if the TP sensor would cause my symptoms or if it is just coincidental. Thanks to all those who respond.
