SOLVED: bad wiring job on trailer brake resulted in limp mode when headlights were turned on.
SOLUTION: over 10 hours of certified mechanic time chasing wires to find the culprit. Wires re routed and replaced. NISMO FIGURED IT OUT VIA INTERNET.
I already cross posted this at TNX but I figured I need as many eyes on this problem as I can muster to find a resolution. Some opinions I've had are either timing belt tensioner or SMOD.
So I just bought my 06 Xterra Off Road (Yay!) and ran perfect for test drive. As soon as paper work is done and I drive it home it accelerates fine to about 40mph but will not go over ~2200 RPM and is slowwwwww to 60mph (Boo!). So I call the dealer and tell them about it but of course the next time I get in the truck it runs fine, drove it all around yesterday and it was flawless. Tonight I get back in to drive to a friends and it occurs again. After being shut off for a few hours I get back in to drive home and no change. I have taken the radiator cap off while cold and didn't notice any signs of SMOD there. I think the dealer may have done a coolant/fluid flush before the sale though so i'm not sure if it's just being disguised. I get 0 CEL and no weird noises on accelerating or anything, at least not that I can hear over the hum of the worn out Duratracs. Thoughts?
