a check engine light came on 2003 camry 2.4L auto. OBD fault code was P2238
the car has 150K miles so I changed the following.
coil packs. Plugs. Air/Fuel ratio sensor. MAF sensor. O2 sensor. + side battery post. the check engine light is now off but I now have a very low idle that cuts the car off at red lights or stop signs. Any ideas on what to do to fix.

Thanks

 

P2238 is a fault in the A/F sensor heater circuit, Bank 1 Sensor 1.

Disconnecting the battery will cause the engine computer to relearn the idle RPM. Keep driving until the computer relearns the idle.
