Running rich

[JMikk]

Hello everyone, if youve seen my posts before you know my ram is a p.o.s
I started working at firestone and with my employee discounts i can afford to start fixing her up! That makes me pretty damn excited! For starters im going to get a full trans service for an amazing price! So due to my new found low prices i need to figure out why the truck is running rich, heres a little info for you. Theres no CEL on and the plugs are newish, cant put a mile count on them because i forget, new air filter, clean oil and good gas.

Dapepper i hope you and your infinite wisdom see this!

How's the idle? Try the key trick to make sure there's no codes stored

Plenum done? Probably fouled O2 from a blown plenum if not.

Plenum was done and with that all sensors replaced, that being said one of my brand new sensors threw a code a few days ago and now the lights off so im confused.

Bad bank 1 will cause rich run if it didn't like the a/f ratio too.

well thats much lighter news than i was expecting, sensors are an easy enough fix

Unplug sensor, see if anything changes.
O2 sensors are a pretty common cause of running rich. I'd suggest only using the OEM replacement which is NKG. The last one I used was a Bosch and while it seems to work, I wonder at how long it will last. IF your plenum was blown it wouldnt hurt to replace both, although I would only do one at a time and see how it effects the truck, just so you can learn more about it. Also check your cat, as a bad plenum can cause it to clog.
