Hi I have been looking all over forums and never found the exact problem with my expy. I have a 03 expy EB 4.6 and the problem is the first start every morning the truck takes longer and longer to start, it cranks but won't start. sometimes it tales up to 20 min. to start. but right before is starts on the message center it says check fuel cap and starts right up. I have checked the fuel cap and it good and tight. but when it stars up the rest of the day it will crank the first time. and also when I try to get up to speed the truck takes forever. and when I get down on it to pass someone it jerks a little bit. I am hoping someone can help me.

Are you getting any check engine light?
Have you had the codes read or checked?
How many miles on the expy?
When was the fuel filter last changed?
