Hello,

Iam new to the site, and wondered if anyone could help me.
I have a 2000 V70 Wagon xc se awd with 120,000 miles. I have a hard time restarting the car after refueling' I have to crank for about 6 seconds , then feather the gas pedal to keep the car running until I can get into gear and go.
The car runs poorly, and seems to want to stall for a short time,( 30 seconds ) then runs ok
I smell rotten egg -sulfer smell.The MAF was recently replaced.
Thanks for any help THIS IS A GREAT SITE

Do you top off the tank when you go to refuel? If so, DONT DO THAT and see if it works any better.

You are flooding the charcoal canister, which causes it to in turn flood the intake manifold with fumes. You may also want to look into a new canister shut-off valve or purge valve, I don't know which in your case is causing that to happen.

Alright, just making sure

When it does that, disconnect this line:

This feeds the fumes from the canister into the intake. You can disconnect it at that white valve until you get it to start, and then re-connect it. If it sputters, you'll know the problem is the purge valve right there on the radiator shroud.

Ignore my other arrow there about the vacuum lines, the picture was for something else.
