Just as the title indicates. I pulled out of my driveway and the Jeep hesitated. I gave it some more gas and heard a pop. Not loud, and I don't recall feeling it. It just seemed like something (gas pedal linkage?) had gotten bound a bit and then let go. I only drove it about a half mile round trip after that, but by the time I got home it was too dark/late to investigate. It didn't drive funny after that, and I've had the hesitation before (albeit without the resultant pop). Any help?
