Hey guys,

I haven't driven my R33 gtst for about a month and it's just been sitting in my garage,

The perol was dangerously low so I topped it upwith $20 which got about 1/4 of a tank.

I went for a drive today (just before) and it's running REALLY rough!

It is really lumpy and when I accelerate there is hardly any power and it feels like it is gonig to cut out.

(I thought at first it was the car about to die due to no petrol but still have the problem after I filled up)

When it's idling it has the same issue, for eg) the REVS go up and down between 800-500rpm.

Just wondering what I should check for as I'm lost as to what it could be :P

Thanks in advance

Couple of questions for u.

Is the oil milky??

does ur coolent look like it has a slight oil patten going though it??

if u take off the centre cover were ur coil packs sit, and look at them while the engine is running at night time can u see sparks jump or it look like a pretty christmas tree??

the petrol u got wasnt from a "no Name" petrol station was it??

i only ask these questions because i had a very simular issue with mine about a year ago. i hadnt driven it for about 2 month started her up and felt like a truck that was 50years old..but i kept on driving it for a few weeks then my head gaskit went. once that was fixed she was fine..

yeah could be a number of things

but i would personally check the most obvious things like spark plugs...make sure they arent rusty... then check the coil by seeing if there is spark at all leads..

check if fuel filter is blocked, sometimes the symptoms of blockages cause irregular idling and drives like shit.

by the way does it rev past a certain limit??? does it cut out?

if it doesnt then it may be in limp mode.....

try reseting the ECU

hey buddy as everyone said it could be a number of things the first thing to do is figger out what type of a miss it is it can only be fuel ignition or mechanical and may be isolated to one cylinder or spead over all.....

firstly if you can compession test each cylinder if all good its not mechanical eg: head gasket or burnt valve

next see if the miss is isolated to any cylinders by briefly disconecting the injector plugs one at a time if you disconect a injector plug and the idle dosn't drop thats your dead cylinder if the miss is located to one or two cylinders its more likly to be a ignition miss plugs coils ignitor ect

if the miss is spread accross all cylinders then its more likly to be a fuel problem so start by checking pressure flow and fuel condision if all this meets specs then it may be a sensor usualy the air flow or coolant temp have this effect

sounds to me like a fuel poblem like water in fuel take your fuel filter off keeping your finger over the bottom fitting so it stays full of fuel then empty it into a clear glass and blow throw the filter in the reverse direction of fuel flow into the glass if theres any water rust or dirt its no good

i hope this helps its only a rough gide but once you figger what type of a miss it is you will have a much easyer time finding the cause CHEERS

    • The values for HID colour are also defined ~ see https://www.legislation.gov.au/F2006L02732/latest/text  ~ goto section 3.9 onwards ....
    • So, if the headlights' cutoff behaviour (angles, heights, etc) are not as per 6.2.6.1.1 without automatic levelling, then you have to have to have automatic** levelling. Also, if the headlight does not have the required markings, then neither automatic nor manual adjusters are going to be acceptable. That's because the base headlight itself does not meet the minimum requirement (which is the marking). ** with the option of manual levelling, if the headlight otherwise meets the same requirements as for the automatic case AND can be set to the "base" alignment at the headlight itself. So that's an additional requirement for the manual case. So, provided that the marking is on the headlight and there is a local manual adjustment back to "base" on the headlight, then yes, you could argue that they are code compliant. But if you are missing any single one of these things, then they are not. And unlike certain other standards that I work with, there does not seem to be scope to prepare a "fitness for purpose" report. Well, I guess there actually is. You might engage an automotive engineer to write a report stating that the lights meet the performance requirements of the standard even if they are missing, for example, the markings.  
    • Vertical orientation   6.2.6.1.1. The initial downward inclination of the cut off of the dipped-beam to be set in the unladen vehicle state with one person in the driver's seat shall be specified within an accuracy of 0.1 per cent by the manufacturer and indicated in a clearly legible and indelible manner on each vehicle close to either headlamp or the manufacturer's plate by the symbol shown in Annex 7.   The value of this indicated downward inclination shall be defined in accordance with paragraph 6.2.6.1.2.   6.2.6.1.2. Depending on the mounting height in metres (h) of the lower edge of the apparent surface in the direction of the reference axis of the dipped beam headlamp, measured on the unladen vehicles, the vertical inclination of the cut off of the dipped- beam shall, under all the static conditions of Annex 5, remain between the following limits and the initial aiming shall have the following values:   h < 0.8   Limits: between 0.5 per cent and 2.5 per cent   Initial aiming: between 1.0 per cent and 1.5 per cent   0.8 < h < 1.0   Limits: between 0.5 per cent and 2.5 per cent   Initial aiming: between 1.0 per cent and 1.5 per cent   Or, at the discretion of the manufacturer,   Limits: between 1.0 per cent and 3.0 per cent   Initial aiming: between 1.5 per cent and 2.0 per cent   The application for the vehicle type approval shall, in this case, contain information as to which of the two alternatives is to be used.   h > 1.0   Limits: between 1.0 per cent and 3.0 per cent   Initial aiming: between 1.5 per cent and 2.0 per cent   The above limits and the initial aiming values are summarized in the diagram below.   For category N3G (off-road) vehicles where the headlamps exceed a height of 1,200 mm, the limits for the vertical inclination of the cut-off shall be between: -1.5 per cent and -3.5 per cent.   The initial aim shall be set between: -2 per cent and -2.5 per cent.
