Default Engine won't idle above 3500

I've of course searched the posts and several other sites, but I came up dry trying to find any info on my problem.

A few weeks back I had a very small fender-bender. Speeds were around 15mph. I rear-ended a mini-van, my airbags didnt deploy, but the glass on my headlights broke.

After the mini-van pulled to the curb, my xc-70 was stuck in traffic, unable to go faster then the speed at which the engine was idling, around 1500.

The gas peddle has no effect and the engine idles at about 1500-1700 with the gas fully pressed. If I pull up on the brake pedal, the engine will reach 3500, but the gas has no effect after it reaches that limit and when in gear it drops back down to near stall levels. My searching has lead me to think it might have been the MAF sensors, but I disconnected them and the engine ran noticeably different, so I've pretty much ruled that out as still working.

Immediately after the wreck the Volvo was towed to an auto-repair shop, but the shop said they didnt have the right codes and that I should take it to the dealer, which I'll do but I'm trying to save on the $160 towing fee.

I've checked all the fuses, so I can rule that out too. Any ideas?
