Hi and thank you for your question.
The first diagnostic test in a situation such as yours is a compression test. This could well be a mechanical problem now created by the previous problem. No matter what it is always prudent to start the diagnostic process of running problems with a compression test. Remember when you are performing the test, ground the spark plug leads (you should see the 3 grounds sticking up on the ignition module box) and make sure you have 2 of the 3 spark plugs installed at all times when performing the test. Hold your throttle wide open while testing as well. Let me know what you find and we can go from there.
