Car started missing and running like crap yesterday on the way to work. When I start it up for may 10-15 seconds it runs fine then starts missing. It is missing the worst under light throttle and under no load. It dosn't see to be vac or a boost leak and I couldn't pin point it to a certain cylinder.

I am wondering if my cas or maybe 02 sensor's might be going?

I would grab a a volt meter and some tools and check the whole ignition system from the plugs to the ignition chip, and all the wires in between. then check the timing, maf and double check for vac leaks. its kind of hard with out seeing the car personally bud.

is the car throwing any codes

The timing was just done like a month ago and so was the maf

I think I might have gotten water in my CAS...
