SO on my way back from chipolte today, my car all of the sudden starts to run really crappy and stuttering and backfiring, then the ASR then the check engine light starts to flash so I make it down the road about 1 minute to my house. It smells like eggs (Cat??) there is a ticking coming from under my car near the middle. Also it sounds like it has a really bad knock coming from the valvetrain... mother of god this car is crap.
any suggestions or help? Obviously I need to scan it but I can't any time soon. So any idea ladies and gents???
