My 91 honda accord shakes hard when i stop and hesitates to drive after stopping

another suggestion is to run the fault codes and find exactly which sensors are faulty and then fix them

stalls? explain all conditions it stalls.
ever give it a tuneup. last 60k, service? or last decade?
after its tuned up, we can fix hesitate.

If the car starts to hesitate at right around 2000 to 2300 RPMs then the EGR ports on the intake manifold need to be cleaned out. The exhaust gas is flooding only one cylinder and causing the hesitation(misfire of that flooded cylinder) since all the other ports are blocked off with carbon build-up. This happen right when the EGR valve opens, letting in the exhaust gas. To find out if this is indeed your problem, remove and plug up the rubber vacuum hose going into the EGR valve and drive the car. If it stops hesitating, that's the problem.

IF IT SHAKES WHEN APPLYING BRAKE TO STOP, THEN YOUR ROTORS ARE WARPED AND SHOULD BE MACHINED TO MAKE TRUE AGAIN OR REPLACED, AND GOOD IDEA TO REPLACE BRAKE PADS AT SAME TIME.

hi first check your wheel balance

sounds like a possible bad ground wire, you will need to find out where these 3 items ground and see if they have a ground point in common.

Does it do the same thing when in Neutral?

engine mounts are loose

I'm no expert but it sounds like it could be a bad motor mount and since it's a 91 it could have rotted out cuz i know honda's have rubber in their motor mounts.
