Hi everyone my 94 celica ST has a idle fluctuation when im in gear and have the fans on. when the fans go off i idle at about 1k. normal idle in park with no fans or accessories on is about 1.5k which I know is a issue, I replaced the fuel filter, spark plugs and spark plug wires, o2 sensor, throttle body and TPS from another celica but I dont think I aligned the TPS correctly? Do you think this may the cause? If so does anyone know how to properly re adjust the TPS sensor onto the throttle body?
https://youtu.be/mmk4e4pkoo8 Im also getting a code 25 which says "The air/fuel ratio feedback compensation vlave or additive control valve continues at the upper (lean) or lower (rich) limit for a certain period of time." And noticing this I had another set of fuel injectors that was off my old celica which ran just fine and put those on so I dont think its the injectors. Any help is appreciated.

I wonder if your problem may be in the ignition, maybe the distributor is going bad. Mine would choke at full throttle just before the cam sensors in the dizzy burnt up.
