Sounds like it is nothing to do with the Cam install now. My car did the same thing, couldn't rev past like 2000rpm's, and it turned out to be some recall at nissan.

take it all apart and install again, double checking EVERY step.

that sucks man, but the cams were so easy to install........

maybe a quick fix?.....try the idle air relearn,  I dont have cams, but with the cam sprocket i did it

thats interesting because i am throwing a code right now, but its for the o2 sensor. when i clear the code, the car runs fine, no ses light. but when i shut the car off, and turn it back on the ses light comes right back on. it still runs fine tho, and my problem is not the same as yours, but thats wierd that if u clear a code and run the car the first time its fine and then shut off and start again and things go haywire. just my .02

its not really wierd that it comes right back on, if you know how the light comes on. both your problems are type A failures which turn on the SES as soon as the emissions test performed is failed, so by it turning on right away just means that the enable criteria for that particular fault is met when ou turn your key on given the specific parameters such as outside temp, coolant temp etc.

i agree with booger his problem sounds more like a valve timing issue
just take it back to the place that "fixed" the cams for you, they can pull the code and follow procedures to get it running right. (and this time it probably wont cost you much if anything cuz they eff'd up)

if its a couple teeth off, then you would be able to hear the difference in the cars idle....maybe sound like a muscle car with a lopey idle...just an example

Please take it back to the original shop because if u do anything to it this may void warranty if u have to reinstall the cams!!
