my jeep has been running really rough, it has misfire on cylinders 1,2 and 3.
I changed the coil pack still having problems, found out the new coil pack was defective.
I then tested the old coil pack and it works fine.
I changed the spark plugs and cylinder 1 is still misfiring.
cylinder 1 has good compression, and i also have good fuel rail pressure.
I am assuming that the number 1 injector is bad?
understand it is a direct misfire or dead hit.
we also checked the fuel injector electrical connector and it is firing properly.
Any other possible causes?
