I filled up with gas the other day and when I went to pull away from the pumps the car hesitated and I had to give it more gas to come out of it. At first I thought I got some bad gas, but it happened again the next time I got gas. I took a quick look around my injectors and fuel rail to see if I had a fuel leak but I didn’t see anything. The car works normal after a couple mins of driving and I don’t have that hesitation or bucking, it just happens right after I put gas in the car. It’s almost like when I take the gas cap off it’s losing pressure???

This is the first time I had this problem since I put in a JDM D15 Vtec into my 98 Civic a few days ago. Anyone have any ideas?

 

Im no expert but are you tightening your gas cap all the way? put some muscle into it. Maybe not enough pressure.

 

When I had this problem my main relay was on it's way out...
