fuel delivery issue

Fishy,x2 on the fuel. If you use ,one brand of pump gas,try another. Or throw a couple gallons of race gas in,see if it acts differently.

Would you (or anybody else) know if they have to post on the pump if it has ethanol in it? I thought they did and have seen it on some pumps but never on Shell pumps so I assumed it's ethanol free and that's where I got gas the last time and it still does it. Next time I need gas I will try a different station just to see how it acts. Wish I had a place to get race fuel close by but the closest place is 40 miles away. Next time I'm going that way I will pick some up and try it also.

Thanks everyone for the tips.
