Need advice...car runs horribly

[986S_in_SF]

Hi all,

Newbie to the forum, and for my first post, have CEL issue while the car was/is at the body shop. Here's the backround... 2000 986 S, 27,000 miles got rear ended a little while ago. Car went to the shop and had both front and rear bumper covers replaced. I go to pick the car up today, and the shop owner says "the throttle doesn't seem to be working..." He starts the car, it idles very poorly, and even when you push the throttle all the way down, it revs slowly to about 2000rpm. For whatever reason, the battery was disconnected and the code must be entered on the radio. It seems like the engine is missing on at least two cylinders, then it smoothes out, still not revving.

Ideas? I know I need to figure out what the CEL codes are, and I'm assuming this will shed more light on the topic. Any help would be appreciated! The car ran perfectly before this trip to the body shop.

Thanks!
