Hey this post is almost 2 months old? What happened to it? My old one suddenly had the same issue so I'm thinking I'm gonna proceed with my upgrade.

Have you checked the coil pack and spark plug on cylinder 3 first?

I hope above anything, you never forget your punctuations. Hahaha. This thread is a little hard to read but... ok, I am still willing to help.

If anything, you should bring it to the dealer ASAP. If not, go to a mechanic you trust. It's hard when the issues are mechanical or something. That's what's running your car.

If you're dealing with classic P0303 symptoms, begin by swapping out the coil and the spark plug. After that, make sure to check the injector pulse and the compression. I hope you've managed to sort it out by this point
