OK so just found out my #4 cylinder is misfiring and has been since I got the car and replaced the COP twice didnt fix it

Is there any easy way to narrow it down between an injector or burnt cylinder without pulling apart my engine??? please help

Sure, check compression on the cylinder. What misfire code are you getting? A p020x, p030x, p035x? Did you swap the plug? Hook a noid light to the injector and see if its firing. You can also swap the injector to another cylinder to see if the miss jumps cylinders.

I know this is probably a useless question, but if you are getting a p0304 and you have swapped the coil twice - have you checked the plug?
