after I did a tune up and changed fuel filter my car ran like crap. I reset the computer and it runs fine other than my clutch being shot

the shaking is likely due to a bad harmonic balancer, and the issues with third gear means you most likely need to rebuild the transmission

I'd put money on it NOT being a computer problem.
