Question: Engine problem 2005 Chevy Cobalt 4 cyl Front Wheel Drive Manual 42,000 miles.  While I was changing my oil today I noticed it smelled like gas especially when I took out the oil filter. Any suggestion on what can cause and fix this? Also, I noticed the pipe just before the cat gets very hot and the piece just after the cat is slightly warm (touchable) just after driving could this mean my cat could be plugging up? Thanks for help
