- 4.7 ho
Hey guys, just finished putting the 4.7 back together and I get an idle of 1500rpms and never comes down even when the temp gauge reads warmed up. When I tap the throttle it revs up but seems to hang there momentarily before coming back down to 1500rpms. I get codes po132 oxygen sensor circuit high voltage bank 1 sensor 1, and p1128 closed loop fueling not achieved bank 1. So I’m guessing it’s something going on with the driver side. Thoughts on the cause or how to go about diagnosing said problem? Thanks for any help you guys can give me cause I’m not sure where to start with this one. I know the battery needs to be replaced, and even though the temp gauge got up to temperature I noticed only the driver side radiator hose was hot. Let me know what you guys think.
