2006 ST Put new intake manifold on it new pcv valve new pcv hose new throttle position sensor new idle control sensor and has new egr valve and maf sensor on itnew upstream o2 sensor. Now it idles high for a minute or so after you start it. Then it idles to normal and after another minute or so will idle so low it almost dies. It throwing a P0171 ( to lean ) code.According to my diagnostic tool the catalytic coverts inst working because the upstream and down stream o2sensors give similar readings could that be it. Thanks
