Yeah Fuji blue was the proper blue though , Mariana is just an imposter really , I had to take second best this time , still better than black mind :joy:

Disagree, Once you go black you never go back, try it and You’ll see :grin:


Hey welcome in. Very nice car you have there!

And sprios is right! Once you go black…

You end up with a shitbrick brown :joy:


Blue really stands out when you have sunshine.

Black paint is a bit moody on a non-curvy body, and it seems to be a popular colour with male car owners in Scotland (i.e there no sunshine ever).

I would ditch those silly wheels and get some quality 18" set.

If you want to “tune” the car, I would at least get the car checked if it had plugs changed recently - and get an oil and filter change in any case.

Remember that the GTO only has 360 cc injectors and a 20+ year old fuel pump, so taking this to a tuner you will likely be recommended to upgrade these before they are happy to touch it.

Yeah i love the blue… those wheels are horrible and will get some originals when i can agreed! Just driven it for the first time and its missing in all gears… so need to get it checked out properly… im hoping it just needs some new sparks… apart from that runs okay! Cheers


I don’t live too far. Well I’m Cambridge but its not too far. I can take a look at your motor, I’ve fixed them before !
Granted I used a wooden spoon and a pair of gardening gloves, but it worked.

Well in all seriousness when I bought mine I had issues that subsequently I fixed with a replacement of;

New turbos
ignition module
fuel injectors
Fuel pump
Fuel pressure regulator
Fuel lines
Fuel misc
intake manifold
Air filter
Air mass meter
Head gasket replacement
Gearbox replacement
Engine rebuild
Chassis straightening jig ( 90 into a pair of unsuspecting wheelie bins )
New tyres
New brakes
New interior

So as you can see its only a small list of things I’ve had to do in order to get my motor up and running :slight_smile:

Now with extra seriousness, I had issues with the ignition module (ptu) and fuel pressure, in fact with a new pump it worked wonders on my vehicle. Anyway would be happy to take a look sometime if you get desperate. You’ve tried the best, now try the rest.

Thanks jerry i may be in touch!


Yes mate no problem.
Jerry :grinning:

Dave, just to clarify, when you say “tune” do you know if the vehicle is uprated / fitted with an aftermarket ecu? Or, as I suspect, do you mean it needs a tune up/service like plugs as you mentioned?

And is the misfiring like a popping as you drive along or do you get noticeable lack of power when it misses


  • John

Im not sure to be honest if its been uprated… yeah tune up like sparks and anything it needs to get it running smooth!
It pops when driving along i have to feather the throttle or it does it very annoying.

Pop with defined loss of power? like it virtually stops going or ?
