I have now replaced the fuel filter and put gas line antifreeze in to eliminate water.

Get this now: It was running fine I floored it, drove it hard, everything and it was good. Then I made a right hand turn and accelerated hard on the turn and it is back to running terrible. Coughs and backfires. This did seem to start at the time when this van was run into on the right front fender (passenger side) but I did not think it would be the cause.

Anyone?
