Engine "Misses" After Plug Wire ReplacementAlthough there could be other causes, I suspect that IF you did not replace the plug wires one at a time, you may have routed the wires to the wrong plugs.

It is critical that the wires go from the PROPER terminal "tower" on the distributor to the PROPER plug.

You will need to get a diagram of the proper terminal tower wiring number pattern, and the proper spark plug numbering sequence in order to reinstall the plug wires correctly.

You may be able to borrow a repair manual for your make, model, and engine at your local library. IF NOT, you can usually buy a manual at any one of your local auto parts stores. Good luck!

You may have bad plugs as well CheckSpark can evaluate plugs and wires in seconds, works on all engines with plugs and wires new or old big or small.

Start by testing the compression. It should be consistent within a few PSI on each cylinder. Any cylinders that have little or no compression probably have a burned valve. If all cylinders are up, check the plugs, wiring and distributor.

What else could be wrong if 2 cylinders are misfiring after getting water into the motor through the intake after the spark plugs and ignition coils have been replaced and it is still misfiring?

I really hate to be the one to tell you the bad news but it is possible that you have bent some valves. Take the spark plugs out of the missing cylinders and run a compression check on those two.
