What do u think is wrong with my car?

Answer
Yes michael your on the right track..do a tune up.. make sure you have spark, run some LUCAS INJECTOR CLEANER FROM AUTO ZONE ITS THE BEST..but its hard to say it could be lots of things, this could could be a gas problem..this could be a missfiring, bad coil, wiring harness or coil connector..when you say shake do you mean missfiring, or running rough??... Just start troubleshooting and just remember its all about SPARK and AIR/FUEL RATIO..ARE YOU HAVING ENGINE LIGHT come on?? I have included a website that can help you with engine light/codes...this will help you pinpoint problems!
