Trying to figure out why I have a misfire on cylinder 2 and multiple misfires. I have changed my plugs, coils and the purge valve. Any suggestions what to look for before I start replacing parts that I don’t need.

 

Important to know year, model and engine .

A better way to determine just what is going on is with the use of a capable scan tool.
What we need to know is : fuel pressure, what other cyls are misfiring, MAF readings , eng temp and a few others
The days of diagnosing with limited info are gone ! There can be several reasons for multiple misfires and the best way to find out why is looking at the data stream info

 

I didn’t get other cylinder numbers, just multiple misfires. It runs a little and then stalls. I haven’t checked fuel pressure because I don’t have a tester. It’s a 2014 expedition el xl 5.4l 3v trinatron

 

Late model vehicles have a different fuel systems as compared to older years. Some have built in fuel pressure sensors that report to the computer and these can only be checked with a scan tool. In either case, a look at the data stream info may be required to come up with a worthwhile diagnosis.
