    Hi guys,
    2003 325ci sport with 52k miles
    I drove the car 2 days ago no probs, yesterday I started car sounded rough then drove up the street really rough and noticed yellow engine light on. Book says "exhaust emission values have deteriorated" any help much appreciated could it be a sensor or coil?? Tried it again today just the same any thoughts?

    You will need to get the codes read and post them up for us to review

    Could be a coil gone down if it was really bad, or possible camshaft sensor, like Neal mentions get the codes read and post them here

    Unless you want to check the coils yourself? you will need some insulated pliers though
