So I had a code stored in the ECM saying bank 1 and 2 are running lean. Ive searched for b vacuum leaks with none found. My sensor volts and short term fuel trim while driving are normal. At idle I'm in closed loop with .1 to .8v on the sensors cold then warm I have no sensor reading in open loop. Once I warmed up I run in open loop with normal stats. I've changed the IAC,MAF, TPS sensor and both upstream o2 sensors without succes. Any idea or is this normalish?
