New to the VG33. What the **** is wrong?

[air_forced]

Just bought an 03 Frontier. VG33ER. Ran perfect for about a week. Then on a cold start it had a very rough idle. I let it warm up for a minute, but was gonna be late for work so i pulled out of the driveway. The car barely moved. Giving it gas up to 3000rpm it was still moving as slow or slower than if I had just let off the brake with out giving it gas. Would not go above 3000rpm and then the SES light started flashing. Pulled over, cut the engine and then fired back up. No problems. This has been intermittent, about once a week or so, for the last month. Pulled the codes and the knock sensor has tripped, and a multiple cylinder/ random cylinder misfire code. I can't figure out what's going on with it. Any ideas?

Ignition module would be the first thing that comes to mind.

replace the knock sensor... should fix it to be honest

there is a nice article in the stickies up top this forum that explains all stupidity of that part

Yep your right. I remember reading that also.

What's the stored code?

It's been awhile since I checked them. Was knock sensor and multiple/random cylinder misfire. Don't remember the codes.
I plan on replacing the knock sensor. Nissan is horrible with those.. Just seems like the problems it's been having can't all be caused by that sensor.
