Why is there cylinder 2 misfire?

It may just be a coil breaking down or a bad spark plug. Try swapping one of the coils over with the faulty one and see if the misfire happens on that cylinder and cylinder 2 runs fine. If it does then swap the faulty one for a new coil. Don't know about your car but most now have individual coils for each cylinder that fit directly onto each spark plug.

Check your distributor cap and rotor, make sure the firing order is correct. Reset timing and start vehicle. Make sure the spark plug wires are ok. Problem should be gone.

On my 99 buick regal ls the # 2 cylinder keeps misfiring, i have changed plugs and wires and the coil, all the fuel injectors sound fine what else could be causing this

alot of times the coil goes bad and kills the driver for the cylinder, remove the plug wire from that coil and see if it has spark if it does then my next step would be to do a compression test on #2 cylinder to make sure its not a mechainical problem. if the compression is good then check for vacuum leaks around that cylinders intake port and last is to make sure the firing order is right.the last thing would be to swap that injector with another cylinder and see if the misfire moves.good day.

Ignition problem car runs on two cylinders randomly

if one spark plug were fouled or one plug wire was arcing to the engine then 2 cylinders would not work, the spark is controlled by the computerif its been 30,000 or sole miles since plugs and wires were changed change them it might fix it but at least you will know it isnt that and plugs would have been close to worn out anyway
