i have a misfire in cylinder 1 so i replaced the spark plugs and coil packs and it still cane up with misfire cylinder 1 so im kind of lost on what to do i heard maybe buying new fuel injectors, (i also ran fuel injector cleaner hoping it would help and it didn’t) was hoping someone could help!

 

what happens if you swap out injectors between adjacent cylinders? Buying all new fuel injectors is a waste of money as they rarely fail -and you can either replace the bad one or find an injector cleaning service to test and clean. What did the plug on #1 look like? How does the wiring harness to the coils look (ie connectors to the coils ok?)

 

What is the compression?

As others have mentioned injectors rarely fail - so I would swap 1 and 4 coil and plugs with 2 and 3 coil and plugs - and see what happens, after making sure there is compression on all cylinders.

Does the car idle smoothly? Does it use/lose coolant?
