how do i tell if i have a bad injector?
i keep throwing a p0300 random misfire.
im thinking it could a bad injector or seal.
or could my header leak have somthing to do with it?

any help would be great.

How do i check if one of my injectors is bad? I have 60's and i get bad mpgs and see fuel in oil.
Thanks

 

Well i can tell u if the injector is bad then the car won't run and will throw a code for the injector that is bad I would check your plugs make sure they r gapped right and clean them up maybe also clean the injectors with your at it

 

If you see fuel in the oil, you have worse problems than a bad injector
