I have a 2000 Odyssey LX on which about a month back I got throttle service done after I faced a typical sticking kind of problem when you initially apply pressure on gas. Thereafter you don't see any problem unless you have released the gas pedal altogether and push it again. That did resolve the problem for 2 months but I am kind of facing that problem again. The service representative told me that the problem could be because of lower grade fuel that i put in. I usually put in octane 87 rating gas. Has anyone else encountered this problem or know of the cause?
