Misfire cyl #6 Help
I have a 2000 maxima and have a misfire on Cyl 6.. pulled codes P1320 and P0306...tried swapping coil next to it which is #4 and still get a misfire on cyl 6 (disconnected plug that's how i figured out cyl 6 still wasnt working)..injector seems to be clicking....next i checked the spark and there is no spark in cyl #6... has new ignition coils and new cam sensor... what else can be wrong? not sure where to go from here..any help will be apreciated..

I have the same problem code is P0306. I am going crazy already changing them coils. And i also have a rough idleing. I was thinking iac valve first. I cleaned it still the same rough idleing. Replaced maf sensor still the same rough idleing. But we checked the compression, i think it only have 30 no more than 40 (psi?)on number six plugs. I was wondering if my ecu is going bad? Do i need to reprogram the new ecu if i decided to get one or it is plg and Play. Thanks again

About the ECU, if it is bad and you get a new one, it is just plug and play.

To test the signal coming to the plugs on the coil packs:
Each coil pack has 3 wires going to it. A red wire, a black wire and some other color wire that is different on all the other coil packs.
Unplug the wire connector from the coil pack. Using an multimeter or a test light:
Red wire - check that you have 12 volts when the ignition swich is in the on position.
Black wire - connect one lead of the tester to this wire and the other lead to ground. You should have a connection.
Other wire (signal wire) - connect one lead of the tester to this wire and the other lead to other end of the wire at the ecu connector. You should have a connection.

I had the same problem, last week. It said misfire in Cyl #1. So i went to the local car parts store, bought someone spark plugs (NGK G-Power) and replace cylinder 1 plug. Ran the car, and the rough idling is gone and the Rough startup is gone. She purrs like a walrus now :P
(dont go crazy with the coils and what not, first thing you should do is change the plugs, it cheapest and easiest. and always!!!!!!!!! use a torque wrench!)
I hope this helped.
