Stalling And Missfire Problem

[Eatan8]

Hey everyone.

Having some major problems with my S2 R33 Skyline Gts-t.

Started off as just a small missfire under 15psi so I had the plugs done coils checked and new Cas put in by a mechanic got it back and it was backfiring and run awful so i took it another shop in melb who i was recommend to due to the wolf 3d ecu they trimmed the fuel changed the plugs again and looked over coils run like a dream for about 2 day and since has developed a lumpy note which sound like a wrx and a very bad missfire through the whole rev range and a few days ago it started stalling when i slowed down nearly as soon as i put the clutch in.

If anyone has any ideas on what could be wrong that would be great.

Cheers

Right .. Well I dont know much but I know a WRX sounding skyline is coils .. so they need to be replaced with either new coils or spitfires.. from what i hear spits are better ..

sorry im not much help but there a short answer to some of it

I was reading today that gtr coils are the best....but costs are higher...therefore you will need to get spitfires...when replacing yours.

On the other hand if coils were checked.....then either your crank angle sensor or something else is wrong....your timing is being thrown out some-how.

Borrow some coils if you don't want to buy them...this will let you know straight away.

I have a set...if you want to plug them in and check...(RB26..are they the same?)I think they maybe.

Done both of that lol, it already has splitfires and had a new cas put in about 3 weeks ago so i have

no idea what it could be, but I have lookin around and the conectors to the coils look really crappy do

you think could have anything to do with it?

Ignitor and cables get alot of heat and can be damaged....also you could be missing because the ignitor is not earthed properly.....Have you got the cover off and the ignitor loose or is it screwed down on cover?

The cost of a new ignitor plus cables is big bucks from nissan...

You will need a car elec. to rewire the whole loom,,,this is a cheaper option if the ignitor is good...

Cant see any other reason this is happening......have you checked your injectors?

Bad pump,injectors and afm's can also play around with missing problems and with afm's running problems...

Yea i was thinking of having a elec lookin at the wires and also because it is a series 2 they dont have ignitor packs which is why u cant put series 1 coils in a series 2, but thanks for the advise i will have 2 have the afm looked at as i think it shouldn't b the injectors or fuel pump due to them being aftermarket parts.

Found the problem, although 2 well know shops said my coils where in good order and because they are splitfire they will be fine it turned out 2 of them were rooted and both shops put wrong heat range plugs in, so put new plugs and coils in car back 2 running 15psi without a worries so thanks for imput about the coils guys.
