2003 Volkswagen Jetta Q&A

2003 Volkswagen Jetta Question: Engine misses and losing power

Out of the blue this morning, the engine in my Jetta suddenly began running really rough and started "missing". It does this when idling - making me think it is going to stall, and then at speed, it was very hard to get her above 45mph - like she had no power. There is a strong smell from the tailpipe. The check engine light is on but I have not yet taken it to a garage to be diagnosed. Anyone have any ideas? -
