Holy Codes Batman..Please help OK. so I have been having some problems lately (fuel related) see following post for more details
https://ls1tech.com/forums/fueling-injection/412504-running-lean-discovered-dyno.html
but I had been running very lean, like 15:1 even at idle. Think I determined that my fuel pump was only supplying about 45lbs of pressure at idle and would drop to about 32 under load.
I had the following codes that are still there even after replacing fuel pump and really need some help.
There is a fairly long list but my SES light only went on 2 times, which I checked and cleared codes with predator.
P0440
P0442
P0446
P0441
P1539
P1546
P0300
P1380
Any help would be appreciated. Maybe a grocery list of things to check. Etc.
One thing I also did some real time data and 2 of my O2sensors showed about 50-125mV value that would fluctuate, the other 2 had anywhere from 825-975mV.
Thanks in advance, Mods in Sig.
