Any thoughts gents. I disconnected the battery for 15min but no luck.

 

2007 Forrester 112000 miles.

 

p0506 - idle speed low.

 

Runs normally.

Disconnect battery for 30 minutes.

hmmm....could be the car was restarted with the foot depressing the accelerator and it corrupted/confused the ECU's expectation for 'closed throttle' at the TPS ?? not sure

 

 

it actually could be a good idea to clear the code, and re-start. Do not depress the gas pedal. The car may crank longer than typical as it will likely need to make adjustments to get to an acceptable a:f ratio and begin completing monitors.

If the CEL light was on I would get the codes read and find out what they are telling you.  Most auto parts stores can read the codes and then once you have the code then ask your questions.

I think I got it sorted. I replaced air filter (waaaay overdue) and disconnected the battery for 1hr.

 

Drove it around the hood for 10min. All good.

 

Fingers crossed.

 

Thanks all.
