Hi guys, new guy here again bothering you, please help me with the following codes:

Looks like a bank is running like crap. Did you replace your Cap, Rotor, and wires? Is so, might be the coil for that bank.

Sorry did not mean to sound like a smart !Removed!, I don't know anything about codes but after researching I found what you guys posted, I have not changed wires nor plugs, should I do that first before I invest in coils what do you guys suggest and where can i buy at decent price.

Thank you all.

Ps what is a cap?

[AcidFire52]

cap is one of the distributer caps.

I would start with plugs, wires, cap, and rotor on both sides.

If you still have issues, then the coil.

If you have a multimeter, you can test the resistance of your Spark Plug wires and igntion coils, and see if they are within spec... :)
