Hey guys

 

I am about to put my 2004 wrx (2.0) on the road

I took it out and was idling it while I washed it

I was not paying a lot of attention but then noticed it was not idling low...not normal

Checked and tach was reading about 1800 RPM

Had reached normal op temp for quite some time

hit pedal a few times...would not drop

 

Any input would be much appreciated

I was thinking maybe the coolant temp sensor??

I don't know where it is of if there is a way to test it

 

No check engine lites but....  1st...my battery was dead for a week..,,,2nd....I only idled it for 20 minutes and took it for a 5 minutes spin

 

 

Does that year have electronic throttle or a throttle cable?

 

If you let it sit a while and cool off does idle return to normal?

Hey fairtax.  I don't know on either score

The throttle body is a little covered by the intercooler....will have to take a closer look

 

I will try starting it tomorrow after work (its at my moms house)

04 is cable.

well...the next day it was idling fine...weird.

Thanks all
