After I put in the new plugs, my car was sounding strange. Next thing you know, I got this code. Has anyone else had a problem like this?

 

Here's a thread about someone putting in new NGK's and getting this code: http://forums.maxima.org/showthread....ght=plugs+0201

Apparent problems with either coil packs or injectors, more likely the former.

EDIT: Check to make sure all the coilpacks are connected properly, snugly with the plug and the harness is fully clicked in to place.

If the code persists, and the engine doesn't sound right when idling, try disconnecting one coil pack at a time and see if any of them don't have an effect.

 

WOW! Thanks for the info! I'll try to take a look at it after work tomorrow. The thought of spending $300 on coil packs suck, but my gas milage has been horible and I've done everything accept change my plugs, and they were in horible shape. Used car, go figure. Anyway, THANKS!
