My 2000 Nissan Xterra is chugging. It was showing codes for a cam and crank sensor. I replaced the cap and rotor, spark plugs, and crank position sensor. Its still chugging. It only does it when it warms up and only does it under load (while driving) but not while idling or reving it up in neutral.

No idea. But wouldn't it run rough all the time if it was timing? It only Chugs when it warms up.

with both cam and crank codes, the odds of both sensors failing are like you getting hit by lightning.

Usually when you get a code for both, it has to do with the timing belt causing the cam/crank corolation being off. Yes, it can cause rough running. I would start there.

I would also get the injectors professionally cleaned. Additive rarely work and have little or no effect.
