Don't know if I should just give up!

Hi everyone! I purchased the car of my dreams 86 PA. The car only had 24k original miles on it. I noticed a shake will idling. I thought It just need a tune up. The car is mint inside and out owned by an elderly women who drove it to church and to the store. So I brought the car for 3K. Drove it home 50 miles away. The car started to shutter when tring to hold speed. So the first thing I did was change plugs, wires, oil change, trans flush, fuel filter, and pvc. Still the same. Drove car for a week and noticed it was getting harder to start. Took to family mechanic which said it need a new fuel pump. Had work done. Starts fine know, also told him about the shutter and rough idle. Couldn't find anything wrong. Told me to have it scoped. Took to shop next day. 1 TSB change Harmonic Balancer & flush injectors. Had work done. Still the same. So then I changed the ICM for kicks. Still nothing. Took car to another shop. Had it scoped again. Still can't find nothing wrong. Wanted me to have all the injectors replaced lots of $. Do you think the injectors would make car shake and shutter? I read a post that said to change wire & plugs. Did it last night. Nothing. Don't know what to do. Can I check the spray on the injectors? Please help!!! Thank you

I replied in the other post about k200G... It works wonders.. Yes if teh injectors are dirty or faulty the car will shake rattle and roll when you drive it. The only other thing that causes shutter is CV joints bad, which with 24K is highly unlikely. Run 2 bottles of the stuff, give it a few good blastes WOT on the highway, keep it there for a while and clean her out. But Dirty, clogged or faulty injectors will cause this. I have been there on this issue.
