This will proberbly be a tune related issue, i would start with doing a full tune up and see how that helps, multiple misfire can often be a coil problem.

Get a scan done to retrieve the trouble codes for the Check Engine Light indicating. Post the EXACT code here and we shall see what needs to be done.

Most parts stores provides free scanning services.

What I also meant to say is that the air bag light is on too. just in case if you think it's an electrical thing. But the codes P0300, P0301, P0302, P0304 with Mod $17 next to them pulls up. Guess 303 is fine? But like I said all misfire codes. Any idea? Look at my post above to see all of the repairs I have made already. I just can't afford a new car at all so it's either this car or a bike.

You definitely got screwed and the mechanics you went to are not worth a second glance.

What has engine misfiring got to do with the transmission? For vehicle diagnostics, engine performance trouble codes takes precedencse over all others and should be rectified first.

Have you checked the timing belt? It could have skipped a tooth.
Were the fuel pressure tested?
How about the spark plugs?
Get a compression test done as well.
