Hi all and happy new year,

I have been experiencing some bucking and poor gas mileage for a few weeks
and we had a great day here in Washington, DC, so I decided to try and do
something about it. I replaced the O2, sensor. and I cleaned the AFM. I even
took off the sealed top of the AFM and cleaned the swing arm. Afterwards, I
started it up and it would extremely "buck" from about 600rpm to 3,000 rpm in
rapid cycles until it died. After examining the engine compartment I realized
that I forgot to "connect" the AFM. After connecting it the van ran great and
has improved gas mileage as well as not "bucking."

My question is: Isn't there an electronic box (stabilizer) that is supposed
to keep that from happening. And do you think that this means I should
replace the box?
