33 misfire, engine light.
Hi Just wrote long post, tried to preview, error. ffs so short post, this time.
T30 2006 man. QR25
After loss of power and checks, drained and check fuel tank, ok change fuel filter.
3 day later, miss fire, engine light,
on scan tool #3 misfire code, running ok. reset.
renew iridium plugs, swap 1 n 3 coil. new oil and filter , as due. plus a/f as well. cleaned MAF sensor.
2 more times over 3 weeks same code on 3.
Also Nissan dealer scanned ok , did cylinder cut out , about even. checked injector fuel quantity seemed ok plus a heap of other checks while i watched. idea relearn as well.
going to service injectors next week and compression test.
225,000km doesn't use oil up to 5k but oil and filter ever 5k. seems to do it around 2400 rpm around town. doesnt stop, or jerk. idle is good.
What year mods effected by butterfly screws???????
any other ideas?
update, nbn died while writing post last night at 12.30 am.

Re: 33 misfire, engine light.
If you swapped coils and it was still #3 then it could be a lead or ground connection.

Re: 33 misfire, engine light.
Under the brake fluid reservoir on the top of the timing chain cover you will see 2 wire lugs under bolts. The bottom/back one is for the coil earths but you could make sure both are clean/tight and no wires broken.
