Diagnostics Help
#21
Updated - Problem solved.
Found 3 codes:
P0157
P0405
P0410
One code is from EGR delete, other from AIR delete. 3rd code was low voltage on O2 sensor on bank 2. Unplugged the rear O2 sensor, didn't make any difference.
Changed the fuel filter, no change.
Decided to change plugs and wires, #7 plug wire fell apart when I pulled it off. The end of the plug wire stayed on the plug, only 10K on the plugs/wires. All of the plugs looked fine, although the #3 plug was loose.
After changing the plugs/wires, runs perfect. Let's hope it stays that way.
Thanks to Phil for coming to meet me and scanning the codes. Thanks to everyone who chimed in with ideas.
