R32 Missing Firing And Having Problems.. :(

[azn_nick69]

hey guys...

i just brought a skyline and its a 32. dont know much about it.. just want to get some advices from some skylines experts..

My car has been running rich and miss firing. so i took it to the mechanic the other day for a compression test....the mechanic said it might be the coil packs, apprently the guy i brought it off done some pretty dodgy jobs on it..so yea.. well my friend had some spare R33 series 1 coil packs, so i chucked them on and brought a new coil harness as well... everything was fitted nicely and all but its still missing firing and when the car revs up to about 3000 revs it just doesnt boost anymore:( just wondering what other problems it could be..all i can think off it would be the spark plugs.. and if i change the spark plugs myself do i have to gap them.. from what i heard was when u changed the spark plugs u need special tools to change and gap them.. thats all..

thanks guys.. if you could give me some advies i will be much appreciated ay:)

cheers:) nick:)

you changed coils before the plugs?

wrong order

If you buy the plugs with the correct gap, you wont need to alter them.

The correct gap is 1.1mm

Hey buddy, try changing your fuel filter and/or checking the flow rate of the fuel pump.

If you don't know how to do that, start with the fuel filter change and see if you get results from that. I would say 99.9% of skylines I see with a low rpm hesitation or missfire is caused by fuel system problems, coil packs usually don't give a missfire until 5000rpm or around abouts.

revs to about 3000 ? if it was around 2800 or 2900 i would be thinking its going into limp mode

exactly what mine was doing (faulty AFM) so i ditched ecu and bought a vi-pec ecu so i dont need afm's anymore

cheaper option for you would be to try a afm off a mates car and see if that fixes it then you know to go and buy a new afm

The correct gap is 1.1mm

im pretty sure the best gap is 0.8.

correct me if im wrong.

20's run 1.1mm gap standard. The reason people gap the plugs down is usually because of increased boost. A lot of people are running coppers gapped to .8mm. Personally I'm running the factory platinums gapped to 1.1mm at .85bar without any problems, but i do have splitfire coilpacks. It's best to run the biggest gap that you can.

Can't edit post. But in relation to the topic it sounds like a fuel miss not a spark miss. Get a new fuel filter from Nissan P/No. # 16400-53J10 and check your fuel pressure with and without the vacuume line going to the fuel pressure regulator.

yeah def faulty air flow meter, i had the same problem,

if u got a friend with a r32 or r33 series 1 only, swap with him and see how it goes,

thats wat i did and found that was my problem

also, re-gap spark plugs to .8mm or so for increased boost,

i couldnt run more than 10psi with 1.1mm and found out regapping helped alot,

lol now im running 17psi on a 480hp turbo
