check enginge lite went on, car running very rough, like if only rnning on 5 cyl, any suggestions on whats going on??????

 

first check Ignition Coil, then check Spark. Lastly Check Injector. i've got some injectors for sale if anyone is interested.

 

thanks, bank 02 ing coil went bad, changed it today...

 

0302 is an EGR code, why did a coil set it off?

 

well, i looked on ecu site & it said something about egr, so i went to double check it , went to autozone & they scanned the comp & told me it was bank 2 ing coil, so i go home & pull out the coil & there was a a burn spot on it, went to parts store & picked up a new ing coil, my 6th cyl was back, what a difference

 

ohm out all your coils. they probably are all bad, and need replacing.

 

what makes u think that?????
what do u mean by ohm is out

 

what does 0302 have to do with the coil? i'm confused...

 

You are a bit confused on the subject so I'll explain. There are two types of codes here. The codes that the ECM will flash on the MIL and the codes that an ODBII scan tool will pull. The later are called "P" codes and are industry wide OBDII codes. The code the Malfunction Indicator Lamp (MIL) will flash is specific to Nissan.

0302 = EGR System Hi/Low Flow (Nissan Internal Code)
P0302 = Cylinder 2 Misfire with the '02' portion of the code indicating the cylinder (OBDII P Code)

So in this instance if he would have pulled the codes through the MIL he would have got the Nissan specific code of 0607 indicating Cylinder 2 Misfire.

 

actually i received a mil code of 0302, it felt like i was running on 5 cyl, so i went to autozone & got the OBDII code , same thing 0302, but they told mecyl 2 misfire, changed the coil, power is now back........ thanks for all the info
