YasMustang00V6

so after changing my harmonic balancer, Pepper is still in the shop. I need so major help with not wanting to drop any more parts because i havent done mt tune up yet....and im not sure if that will stop my engine from shaking.

I have 4 different mechanics and 4 different analysis. One out of 4 has owned a mustang, and the others may or may not have worked on one.

I am trusting my mechanic, Carlos, who has owned a mustang with the duty to find the root of the issue.

When i first bought the vehicle the owner said i needed a tune up and that would stop the engine from shaking....i have yet to do so.

so my question is Should I or Should I not get a tune up???
and If pepper does get her tune up....and the engine still shakes.....what could possibly be the reason....
the mounts are good, says Carlos, he will have to do a full check on my vehicle at no cost to me because he wants a good review....lol but he is definately a good guy because he was mad that the engine still was shaking even after he changed the harmonic balancer.

Im getting despraate for answers and solutions but i am being optimistic at the same time.....pretty much im frustrated that pepper isnt running smoothly....


******anything to help pepper get on the road and me out of this Pontiac Grand Prix!!!****
