After my 03 jeep liberty warms up to normal, the idle begins to fluctuate until it goes down to 500 rpms than wants to shut off but revs itself up to stay on, now when I am in park and rev the rpms up it...


It's not a gas pedal, it's an air pedal. Fuel injected engines are all about air flow at idle. take off the intake snorkel and check out your throttle body. You may just need a new throttle position sensor, or the Idle solenoid that regulates idle air flow is stuck. The computer will try to compensate, but it can only do so much.

I have a 2007 Ninja 250F. When I give throttle it wants to bog down and tries to shut off. I am assuming the ports and carb need to be cleaned, is there a filter anywhere I should be aware of.


Check and if necessary replace your air filter. You will find it, just follow your intake from your motor back (or check your manual for location). If this has happened after the bike has sat unridden for a while it may be a fuel related restriction.
