well i changing out my lower intake manifold gaskets today with power intake gaskets pic:
i also replaced my plugs with NGK iridiums and did a compression test. everythings goin fine each cylinder was averaging about 1325-1400kPa which is above normal 1275kPa. so i put everything together fire it up and misfire. no code but i knew it. take everything apart to find that one coil boot has no electrode spring in it so i look everywhere for it and nothing well long story short i have to wait till monday to order it

 

Not sure what to say..Good Compressions #'s......That sucks man...Hope you got a beater to drive till then?

 

well i found the spring electrode for the coil put it on and still the same sh*t. So i stop and look at the everything i still hear a misfire of course let me check the coils while the car is running no i din't shock my self been there done that. i disconnect #2 engine speed drops so i connect it back, #4 nothing hmmm.... so i disconnect #6 and engine speed falls so i swap #4 with #6. now number #4 is working and #6 isn't. i take off the boot and try to arc it nothin. So it's my coil I will be paying Nissan a visit tomorrow morning and then its
