I have a 92 accord. For some reason when i drive the car at a constent speen it has a studder. I have replaced the fuel filter, plugs, wires, dist cap and rotor buton. The car is up to date on the oil changes. Its not putting out any codes. Thought it might be a suspenion problem. but I did the ball joint, tie rod ends, sway bar end links, rotors and pads. I did hear that it might be the motor mount. Something to do with the vac line going to it. Has any one had this problem? Any help would be greatfull. I love my honda and have owned a bunch of 88 and 89 accords. First one with this body style.

 

A common problem with accord engines is the egr system gets plugged up on the intake manifold.

Overtime, carbon plugs the passages and the car can shutter. Cleaning them will definitely help the engine run smoother, but this may not be your problem.

Google T2T013.pdf to get a good set of instructions on how to clean those ports.

Good Luck.

You can put your finger under the cap of the EGR valve and manually lift it.
The engine will stall or stumble severely at idle if the ports are clear.
