R34 Newbie From Nsw

[aaasaint]

Hi all.

I have a problem with my R34.

My car has full 3inch exhaust and dump pipe, apexi power fc, K&N air filter and is run at standard boost. Note: The extras have just amplified the problem.

1. For some reason, in approximately the first 30 minutes of driving I will get random misfiring? (engine sounding like a WRX). Sometimes it starts like it, then goes and some times it just cuts in whilst driving. It is usually worse during winter and cool weather. Considering most of my trips are less than 30 minutes, it happens a lot and is quite annoying.

When this happens, the smell of fuel (sulfur smell) is stronger.

2. Also when up around the 4500 - 5000rpm mark the car (when warm) just seems to give out, sort of misfiring.

I have had mechanics check out the coils + tuned etc, they had the car for quite some time and they couldn't seem to find the problem. They said the coils looked fine, it must be something trivial.

I am not really mechanically minded. I only really know what I have been shown which isn't much.

I have read through a lot of older posts and wondered if taping the coils etc will correct my car problems or should I find second opinion mechanic and have re-tuned etc.

I love all skylines and can't stand the thought that my car is running shite.

Have also posted this in the general maintenance section.

Any help would be greatly appreciated!!!

Hiya! Welcome on a sour note! sorry for the pun... not funny...

Best to check it in with a Skyline specialist ie. Garry at Just Jap, Alistair at Powerplay Imports, and then there's Bel Garage, Croydon Motorsport etc.

Which part of NSW are you in? Has the ignition module been checked?

Why go to a mechanic first ? - there is a simpler self-help solution that may save you being ripped off or paying money for nothing - does your engine check light on dashboard flash when you have the problems?

if YES - then the first thing you do is check what code is flashing - it takes about 2 minutes and all you need is a piece of wire 50mm long inserted into the correct place in the drop down plug below your dashboard - search this site for HOW TO CHECK ENGINE WARNING CODES - I don't have the patience to explain everything for you and its something you need to learn to do!

The flashing code will tell you where the problem is - google and d/l the R34 Engine Service Manual (14 mb size) for extra info

E.g. Code 21 is coils problem.

Don't waste time on coils unless you definitely get Code 21 appearing. Could be other issues - they are all listed by code in the Manual.

Get to it - its easy to do!!!!!!!!!!!!!!
