Wow, its like a word mystery.

Use punctuation so we know where one thought ends and another begins.

From what I can gather, it feels like its misfiring, it jumps when you hit a bump, and you have recently done a tune up.

Is the SES light on at all? Have you had a scanner hooked up to it to see whats going on?

ok, sorry for the lack punctuation. I had a scanner hooked up and it told me CPS we replaced it, but didnt work. So now im thinking fuel related causing a misfire, but trying not to tackle a fuel pump until i know for sure.

find out your fuel pressure. Is your pump whining really bad?

Fuel pump isn't that big of a deal, also make sure to check your fuel filter too.
