Hi I have a 1989 chevy camaro with a v6 2.8l multi port f1 engine.my rpm gauge is bouncing all the time.as soon as I start up while driving when I stop it's always bouncing.at 50 mph the car starts to shake idk if that's related to it or not but it happens until I put more speed on it.also while driving today I reached 30 mph then the rpm gauge rose up but the speed started to drop it's like my transmission went out until I put it in neutral then back to drive and I speed up again.I don't know what to do please help

scan for codes, check trans fluid and check for a vacuum leak.
