Out of control throttle
I just reinstalled the fuel tank on my '03 K12GT after replacing the fuel filter. Had the battery out for some other work so after bolting in the tank and re-installing the battery, I reset the TPS.
Turned on the ignition and the engine ran straight up to 8000 rpm. Shut it down before it red-lined. Inspected the throttle cables and they don't appear to be hung up, pinched or mal-connected anywhere. I thought I did something wrong when resetting the TPS so I removed the battery and called it a day.
This morning after re-installing the battery I again reset the TPS and the same problem occured. Removed the fuel cell again and inspected underneath it for other signs but found nothing.
I've checked the hoses (twice) and they all appear to be installed correctly.
I can get the RPM's to go down to 5000 by forcing the throttle handle more (?) closed. Odd.
What the hell have I done?
