Hello All, Just bought a 2004 Copen this weekend. 600 problem free miles, however: got stuck in a traffic jam for about 20 minutes- had to keep crawling in first gear. After 20 minutes the engine was... kinda funny: I had to rev very hard to stop it from stalling and there was engine judder while pulling away in first gear. Engine temp was just fine, no warning lights. It didn't stall but it felt like it wanted to. Any ideas on the potential problem would be greatly appreciated. Car ran just fine once I got through the jam.
