| You can read the plugs to see how the engine is running. If you have fuel leaking past an injector seal you will have one carbon fouled plug. If you have a vacuum leak you will be able to see it on the plugs too (running lean) If that checks out, and your ignition timing checks out, you may have some electrical issues (sensor related)
