2005 titan won't rev pass 3000.

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
