Message However, if you have a Lean Running Injector, the ECU will Richen up that bank to get the average proper.. So now the some Cylinders are running rich and some lean on the same bank.. that will cause a Miss..

Might be able to read the Plugs..

Pull the Fuel Injectors and have them checked and cleaned.. Might be a fuel balance issue per cylinder..

Idle Cylinder Drop test might figure out where it might be..
