alrighty guys, so I drove my car to work this morning, it ran perfectly smooth, I actually thought to myself on the way to work " wow, I really love my car" when I leave work today, I fire it up, and it starts shaking, and the light starts to blink about a mile down the road, I pull into autozone, and they run the OBD for me and its code P0303. Those of you who have experienced this, what did you find to be your answer? I've searched, but I haven't found anyone who posted what they found it was, I know its a misfire in cylinder 3, but its just odd to me that it would be running so wonderful, and than just crap out. Guess I'll start at plugs and work my way from there.?

Has anyone else had this code? What was causing it for you?

any way to test a COP with a meter?

Partially,

See the "sticky" here...

Replace coil + plug on cylinder 3 and be done with it, no sense on testing COPs and all that crap

Make sure the boot isn't melted I had a bad misfire and that's what it ended up being. If that's good, then replace the whole coil.

replaced the plug, and it smoothed out, ordered a set of coils. the plug really smoothed it out, and i shut the light off with my tuner, coils should be in tomorrow after 10 AM.
