How to Troubleshoot Engine Issues in a Ford Galaxy?

I recently purchased a Ford Galaxy and have been experiencing some engine issues. The car seems to be running rough and I can hear a ticking noise coming from the engine. What steps can I take to troubleshoot and fix this issue?

First, I would recommend checking the spark plugs and ignition coils to make sure they are in good condition. If they need to be replaced, it's an easy and affordable fix. Next, have a mechanic check the fuel injectors and fuel filter. If they are clogged, it can cause engine misfires and rough running. Lastly, I would suggest getting a diagnostic test done to check for any other potential issues.

I had a similar issue with my Ford Galaxy and it turned out to be a faulty oxygen sensor. This caused the engine to run lean and caused rough running and a ticking noise. Have a mechanic check the sensors and replace any that are not functioning properly. This should fix the issue.

If the issue persists, it's possible that there is a problem with the engine itself. Have a mechanic do a compression test to check for any internal damage. It may be necessary to have the engine rebuilt or replaced if this is the case.
