Maybe water in fuel? Does it happen when the tank is more empty?

u know...it happens when i fill up now that i think about it...like i just fill up pull out get mabey 100 feet to the light and itl do it....wow i never thought of that

could it be the gas im putting in? its shell incase that helps

Try one of those fuel additives that removes moisture. The only one I can think of is heet. I'm sure there's more...

Good Luck, Eric

IAS motor going bad?

Based on what you said in the last post, it could be the evap system. If the purge valve doesn't work to let the charcoal canister empty back to the tank, the fuel condensation maybe backing into the intake. You can test the purge valve and check the lines going to the canister. There shouldn't be large amounts of fuel.  

I got some shell gas last week and it caused my motor to fluctuate about 500 rpm.....the tank only lasted about 100 miles cause i had to keep it to the floor the whole time on the highway....it was horrible. I'd try different gas cause I did and everything is back to normal.
