Rough Engine idle after Start

[Travelmind]

My 02 Boxster have been running just fine and then it sat Idle for about 2 weeks. I started it this morning and noticed it was running very rough at idle...sort of like half power or bad gas. I backed it out into the drive way and said this is not right and pulled it back into the garage.

My question is?

What should I do.... Try and drive it to my auto repair shop or have it towed which will cost about $100.

Any thoughts would be helpful are suggestions what the car problem could be?

thanks everyone...
