Hi guys and gals.

Here's the back story, Had my skyline yellowed and didn't have the time to get it off till recently (been bout a year).

The whole time the car was off the road i started it every other week to let it tick over (plus i love the sound)

Finally got it squared away and it passed the pits first time yay.

But just recently cylinder 5 has been cutting out WTF?

I narrowed it down to cylinder 5 by pulling out the plugs for each coilpack until the missing sound didn't change. I originally thought coilpack so

I changed pack 4 and 5 around but cylinder 5 still dropped out but 4 was fine. so i changed around the plugs same again. Sprayed all plugs, coils

and connections with contact cleaner still nothing.This is really giving me the shits as it happens on and off so im thinking either ECU or harness.

If anyone has had this happen to them, has an ideaor has a coilpack harness I can borrow to strike that from the list I'd love to hear from you.

Cheers people

what was the plug like? if it wasnt black from fuel i'd be looking at the injector and associated wiring

[Gabbo2047]

plug wasn't black but neither were the rest of them. Did a check on the injectors all working fine. im thinkin ecu might be cactus.

Any one got an auto 33 ecu laying round i can use to check it???

series1 or 1.5/2???

if series 1 try getting a hold of ignitor pack to try as well cause my 32r was dropping cylinders 6 & 4

and did the same thing changed plugs coil packs even did other things then chucked on a different ignitor a pow all fixed

Got a auto ecu here if you want to check it, I'm in rockingham

[Pal]

How did you check your injectors. Could be blocked but still ticking

[Gabbo2047]

At this point in time I think i need all of you to form a line and kick my ass .

I finally got round to checking the ecu with the help of a mate and it turns out the harness plug wasn't

all thje way in on all sides even though it was bolted in. It must have been done when the inspector at the pits had the kick panel off

having a look to make sure the ecu was standard I'm guessing, as i didn't have this problem

till I got backfrom the pits. So far the car hasn't missed a beat so fingers crossed that was the problem

and not something else.

Thanks to everyone for your help Ifeel like such a dumbass .

Cheers
