Hey gusy im not sure what my mileage should be in my 06 4x4 Titan. I hear 14 to 16 at best but i feel im not even getting that. i will have to do the math next time i fill up. If i am having MPG issues what are some areas to start looking at to try to fix it.

Would cracked manifolds give a code??

Cracked manifolds (both sides) didn't throw any codes on my Titan. You have to listen for the sound and smell at startup and watch the MPG. Mine also started overheating when towing up a steep mountain. That was my final clue that something was off.
What's the sound like?

It's a ticking sound, mainly for the first minute or two after a cold start. If they're real bad they'll tick non stop. Don't confuse the sound of the injectors and cam followers with a possible bad manifold.
The p0420 and p0430 codes won't appear until the cats have been compromised from the engine running too rich. You could also get a code for the engine running too rich, but it's usually just the codes for the converters.

Also need to make sure that your O2 sensors and good. They will make it run to rich and cause bad MPG.
