Lexusmikes Posted November 18, 2019 Share Posted November 18, 2019 Need some help.I changed out throttlebody for an aftermarket one and keep getting this code P0505. My 2008 Lexus is250 idles at 2000 rpm cold start in the morning, then comes down around1000 RPMs in about five minutes after warmed up. I was having previous idol problems and that’s why I changed out my OEM throttle body to an aftermarket one. Anybody have any suggestions?
