big mis in R33

[walkoau]

ive changed my plugs, checked the coil packs, even checked the resistance of the coil packs with a multimeter. every thing seems to be normal. the miss is still there. only under a fair bit of load though, so it looks like im going to have to buy a s-afc

i think robo is right! it must be dumping to much fuel......

i know what u mean dude, funny thing is i am a mechanic. (a heavy vehicle mechanic though) so i only know diesl!!!!

and electrical isnt one of my stong points.

i did check all the obvious things first, but its good to get other ppls opinions and maybe learn from others ppls experiences.

looks like i will have the problem sorted out when i get my hands on an apexi safc.

thanks for your help guys.

yeah the safc helped the problem but its still there cause i havent had the chance to get it tuned yet.

you should do a check on the coils yourself before paying to get new ones.

the best way to check shorting is in the dark.

Park up your car at night, start it, and have a look for the little blue sparks jumping onto things.

Get someone to rev the engine if you have to.

I did this on my Ford Fairmont (which I am selling, and buying a R33 R34 4 door skyline) and I could see the little blue sparks jumping from the leads to the engine head anything metal etc.

Definately needs a tune, with the SAFc set to zero, its like its not even connected.
