Put a code reader (static test, engine not running) on it & it came up with the following codes:
P0174 Bank 2 Lean
P0161 ??
P0306 cyl 6 misfire
P0141 O2 Heater Bank 1, Sensor 2
P0118 Coolant temp, sensor circuit, Hi Voltage

SO, I replaced plugs, wires, including coil wire, rotor & distributer cap, still does it. skips, misses under load (acceleration)

NEED HELP?

What else do I need to replace?

On any missing, ALWAYS start to check for a vacuum leak. Plastic or rubber hoses do not last forever. Heat and cold extremes will cause them to crack. You can use brake parts cleaner to spray lightly around the hoses. When the rpm's change, you found the area to search in.
