I have an 95, 850 turdo, 150k, Today, it started to hesitate under acceleration. It starts fine and idles perfect however when I try to accelerate it really bogs down. It will eventually get up to cruising speed but it takes a while. I put a new fuel pump in a week ago, the fuel filter has about 40K on it.

The only code it shows is 440 Evaporative Emission but that been on for six months with no issues
