I have a honda CRV 2000 with 140,000 miles automatic transmission. I recentlyhad a new timing belt put on at the dealership ever since then our check engine light keeps coming off and on I took it back in and it came up that all four cylinders are misfiring so we have put new spark plugs, plug wires, distributor cap, rotor, ignition coil, and fuel filter nothing has fixed the misfire. The car seems to run fine we have noticed a slight drop in our fuel milage. What could this be? Help
