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.

K added my new gasket, only did the throttle body to the intake manifold for now. That resolved my idle issue, however I cleared the code and it came back after about 80 miles of driving, I thought it was fixed but after 80 miles it came back lol. So I know I still got a performance issue and still some flucation when driving and below 2k rpm. so think its still the IAC or the position of the TPS sensor, I think it will need to be reset. so ima try that. I may also buy a new IAC.
