Draining gas tank on 2010 Kia Soul 2.0L and hesitation/misfire questions

286 Views 6 Replies 5 Participants Last post by  56chuzz
I have been having problems with my car acting like it wants to stall when I come to a stop/slow idle. The car feels like it's going to die and chugs/hesitates when you go to give it gas. This has been an ongoing problem for a while and a very long story on "mechanic" repairs. Anyway, I'm wondering if this problem could possibly be due to water and/or residue from yrs of very poor quality gas and times of no use (I'm in the DR)? I was thinking of draining the gas tank once it gets low next time. Any thoughts are helpful as the "mechanics" here are terrible. And if it sounds like a good idea to drain it, wanted to see which of these in the pic is the correct drain plug? The pic is reversed...the black plug is on drivers side and white plastic plug is on passenger side. Also, in the 2nd pic you'll see that the washer/gasket behind the plastic plug is not in good shape. That said, it doesn't leak gas. I've never drained a gas I need to do anything else other than drain the tank, replace the plug, and then put new gas back in? Not sure if anything needs to be done with the pump/filter or if I can just leave the back seat on and just drain away and it's that simple? Thanks again for any help.

I've never drained one like that either, and I don't think I would. Used to be, way way olden days could siphon out the filler neck but that hasn't been an option for a long time.

What about finding somewhere on the discharge of the fuel pump to disconnect and using the pump to empty the tank? Or remove the pump assembly and siphon it out of that top hole?
How much gas is in it? If it's low just refill with good gas and add a bottle of techron.

I agree with Hammerhead. Techron is great stuff. And I don't think either piece you have circled is a drain plug for the gas tank. Those look like body plugs that would be drain holes for the rear hatch area to me.

Thanks. I'm in the DR so not sure I can find techron, but I have tried 2 bottles of good quality fuel cleaner in the past and that didn't do anything for the issue.
Those pictures are not of the gas tank, the gas tank can be seen in front of what the picture is of.

Exactly. That's the floor in the rear hatch.
