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.

vavAlepVav. The OP has the ST engine and the tps calibration you posted is for 2.2 L motor. Is procedure the same for both. My ST is idling rough only on occasions so I am following this thread as well.
Thanks in advance. |
