2002 Dodge Ram 1500 Question: check engine light came on,code reader says misfire on #3 cylinder

i would look at the wires, cap and rotor. all these are bascis of a complete tune up.
this is a good start before talking about injectors or something else.
thanks for using repairpal

2002 dodge does not have distributor cap,rotor, or plug wires. I have changed plugs and replaced the coil pack on #3 cylinder to no avail.

the 4.7 litre engine. I have 90,000 miles on the motor but it does'nt use any oil or run hot also there are no ticks or knocks in engine.

the codes that are displayed are a best guess estimate of the missfire. it may be another coil that is missfiring..
i suggest a shop to test all coils for failure to be sure of the problem.
