    Question Jerking occasionally while cruising?

    Cruising on the highway today, and my Rex would shudder/jerk for a split second every now and then. I was thinking it might be because I was getting low on gas (just above the E mark), but there was no low fuel light (if there even is one). I found the closest gas station, put in some STP fuel cleaner, and filled it up with 11 gallons of 91 octane. It hesitated again on the way home, so I'm hoping it was just some gunk at the bottom of the tank.

    Any ideas? Is there a low fuel warning light (it's 2 degrees out, and am too lazy to go check the manual)?

    That would be the good kind of jerking. I'm not getting any pay-off from this one.

    Checked the air filter box, and there was a little bit of ice/slush at the bottom. Removed it and have driven about 150 miles with no hiccuping... we'll see how it goes.

    Fuel pump

    look into getting a new fuel pump. This happened to my 03 wrx on my way home from one of my trips and stopped for a while then continued later on. Once I replaced the pump, I had no more problems.

    I've seen/heard this issue, many times, as well. But appears his issue was crap in the airbox.
