Today I changed the intake gasket, cleaned the throttle body, cleaned the MAF sensor and replaced the air filter. I did all of this because I have been getting codes P0171 and P0420, the shop said I needed to replace the gasket and possibly replace the catalytic converter (I replaced it with an after market part around 26,000 miles ago). After doing all of this I drove the car around a bit (about 4 miles). I noticed in "Park" the car idles at 1000 RPMs, I thought it was idling closer to 2000 before, but maybe because it was a lot colder then?
So does 1000 RPMs seem too low for my '06 Corolla? I checked under the hood and looked through the Haynes manual and did not see anything about normal RPMs when idling.
