Have a 2005 titan. Idles and starts fine. If you try to drive it it will only do 30 mph or so and runs really bad. If you rev in neutral it wil rev to 2500-3000 and misses and shakes when it starts missing one bank goes lean .60 v. And the other goes to 2.2. At idle both banks are 1.5. Fuel pressure is 58psi Any help would be appreciated. Cats have been gutted also. The rest is totally stock

Thanks kerry

I have swapped the relays and still no luck. Anyway to know that you are in limp
Mode? I have a snap on modis scanner. It shows only p0300 random. Misfire it has a leaking exhaust manifold gasket and a busted trans mount. But can't see them causing this. Any help is greatly appreciated. Willing to pay

Tried the battery disconnect. Still no luck. If I rev it it goes to 2000 and sometimes 3000 rpms and shop smells really rich of fuel.

OK if there is any Nissan tech out there that would be willing to help. I'll pay a tech fee Not looking for anything free. Don't care if it's a 100 dollar fee. If you can help pin the problem down

Wow no one ???? Ok. I started today if I go 3/4 throttle is revs to about 2300 sat there for 15 seconds or so and then climbed to 3000 rpms and sat there a lil and came back down. Doesn't act like a limp mode and smells extremely rich. Fuel smell everywhere

Would that stop it from reving. Guess I don't do much Nissan stuff. But just seems weird that would cause it

Guess that's why I love my diesels. Nissan seems to have some crazy strategy
