Recently the Service Engine Soon light comes up on my 99 Maxima GXE.
A mechanic did a scan and the code is P0301: misfire detected, Cylinder #1.
He told me that I need to replace at least one ignition coil and best of all,
all 6 ignition coils, which is very expensive. My internet research indicates that that's a common problem for all 4th generation Maxima and it's relatively easy to
replace ignition coils DIY.

Has anybody done this before? Where can I get a good price for the parts/ignition coils? Somebody said I might be able to buy a set below $300.
But where? Any recommendations?

 

Replacing the coils is easy to do. Agree , replace all six, else you'll be changing another coil soon or worse (having a misfire without any codes, not knowing which coil it is). I bought mine from Courtesy Nissan for around $56 a piece. Received the Mitsibushi ones and haven't had any problems since installing them about 1 year ago.

 

theres a set on ebay 4sale for 240 i think, dont recall what brand they where. check seller: yoshisakura16. good luck
