idles fine when you try to speed up engine it just bogs down. Changed throttle sensor, fuel filter and still the same checked intake for leaks and vacuum lines

Check the fuel pump pressure AND flow rate. Also check the exhaust system for blockage. A partly plugged converter or muffler can cause a similar problem.

If the suggestions SWilliams and you have a distributor, make sure it is properly advancing. You can check this with a timing light.
