My truck now throws a code 1314 which is cat converter. I have a backpressure gauge and it reads 1psi back pressure on both sides. I am getting tired of working on this thing but I have no choice but to continue fixing her. Any ideas?

 

Sure, how many miles on your truck and what went wrong with your right bank, cylinders 2,4,6, and or 8 that caused the cat to fail?
Depending on your miles, you can replace one or both, pretty cheaply.

Misfire Likely To Damage Catalyst, Bank B
Doesn't mean your cat is bad, just that you had a mis-fire that could damage your cat.

How many mles?

When was the last time you changed plugs and wires? and with what brand?

 

"Likely" is not in the fault code for a 1314, "Damaged" is.

 

One thing I forgot to say is when I put the plug wires on it was dark outside. All I had was a flashlight and eveidently I mixed up wire 7 and 8. Put them on the right coils and reset the code and it runs like a dream and no code. Next up, blower motor issues.
