3.0 V6 fed. 137 K mileage
Also lean and rich bank 1 codes 171-172 Cleared codes and now has low count of ramdom miss on all cylinders on missfire reading. Engine running rough and miss at idle and low speeds and slow take off. Runs good at higher rpm. Any help or ideas. Thanks

Lets start with the basics, when was the last tune-up and what did it include... plugs, wires, coils?

Found problem. Rear cylinders at 210 lbs and front cylinders at 110 lbs. Front camshaft must be out of time or belt slipped.

That extra 100k will make a difference! Good idea to check the compression. Let us know what you find as the cause for the different readings!
