We are having a problem with are 97 Ranger hit has Been setting off the check engine light we had it tested and it told us that the # 3 cyl miss firing we have changed out theplugsand replaced the wires plus the coil pack but We still get a code that will say #3 cyl or muti miss fires.
Does any one have any ideas what it could be

You may have cracked a plug putting them in. Did that once. Was baffled for a good week before I thought my new plugs would be broken. Lmao

A faulty injector will throw the same code.

My dads 3.0 was the same way and turned out to be the injectors on the cyclinders were bad. I dont know what engine size you have but thats what it could be.

Welcome to the site, Bro!!!!

Find someone that has a scan tool and compare the injector pulse on cyl #3 VS the other 5. You'll probably find that it's out of spec. It may be clogged but that's unlikely having 1 plugged and the others fine. Most part stores stock your injector.

take a long screwdriver and put one end up to your ear and touch all the injectors they should all sound the same. If the plug smells like fuel and your getting spark seafoam it then do a compression test.
