Okay. First of all this is what i want you to do. Measure your voltage before you jump to conclusions. I had this problem It was my rectifier plug got a little loose it wasn't putting out 14 volts until 5grand.

 

So under 5 grand it was choppy because it was misfiring, It idled but felt like crap. After that i would check FPR and maybe Seafoam see if anything changes.

 

unplug the power commander it could be the issue also.DOnt just zero map it.

 

Since its only got a KandN filter he just zero mapped it and said it would bypass the PC. How do i check the voltage? sorry im new to all this stuff.

 

it will NOT bypass the pc ,the signals still go thru the pc..If its bad you will still get bad signals to the ecu even with a zero map

 

Ok. I will try to disconnect it and see if it helps. Is there a tool at will measure my voltage? How would i check it? Will my PC tell mw my volatage?

 

I have found a very high correlation with low milage F4Is and bad Fuel Pressure Regulators from hours of research on the topic. MAKE SURE THEFPR ISNT LEAKING EXCESS FUEL INTO THE INTAKE VIA THE VACCUUM LINE.

 

Ok so i went to do a voltage test and when i went to start the bike i noticed it sparking at the ground on the battery terminal. Upon further investigation i saw the screw was just laying on top not even screwed in so everything on the ground was loose. I took my battery to get chaged and changed my oil which had no gas mixed in it. I will b going out to try to start it up right now. I really hope that was the problem. Next step ill be checking the FPR if this doesnt work.

 

Well i fixed the ground but it had no effect. I check my volts and everything is AOK. I'm thinkin its prolly the FPR. I will disconnect my PC and if that doesnt work ima ghost ride my bike off a cliff.
