CHEVY POSSIBLY MAF SENSOR OR WHAT

1989 Chevrolet Camaro

Engine Performance problem
1989 Chevy Camaro V8 Two Wheel Drive Manual 168999 miles

I have a 1989 5.0tpi iroc z. I have had vacuum line problems before and thought this was another one of them. Car idles a little high at times. When under load of any kind it acts like it is misfiring. All plugs and wires are new and distributor, cap, and rotor new. When I hit a bump it will sometimes correct the problem till I hit another bump. All vacuum lines have been checked and replaced. I have no engine codes at this time. And the gaskets at the plenum and runners have been replaced to ensure proper vacuum. I have exhausted all my options. The thing that puzzles me is the fact its not all the time and I can hit a bump in the road and this will trigger it. Thought possibly loose wiring but I don/t know where to start. Any help is appreciated!
