High idle & running rich
 

Hello:
My 04 is has a high idle for about 2 minutes when have a cold start. It is not rough, just on the high side. After 2 minutes it is normal. Is this normal? I live in Fl so the weather is very warm. It reminds me of when I lved up North and the car had to warm up.

I also have 2 codes, L & R banks running rich. I have cleaned the throttle body, MAF and the Throttle contral valve and the codes still pop up.

Any suggestions, tips, etc would be great.

Thanx!!

O2 sensors. Pull them test the resistance in them and if need be replace them

Thanks!. Would yo know how Many O2 sensors and where they would be located?
