Now i replaced the coil and leads already, so hopefully the new ones aren't damaged.
I'm afraid we're talking in circles
you already established that the fuel pump has been "tested"
how??? what methods were used to reach the conclusion that it's "good"?
what methods were used to determine that the O2 sensors had "high resistance"?

I realise that you're not the one that is performing the work and just relaying what the mechanic told you... but without finding out specific details, all we can do is speculate and go back and forth like this
I can't emphasise enough how important it is to provide specific details to us so we can give proper advice... as soon as we get specifics, we can assess your mechanic's competency and advise you what to do

If you clear the code and go for a drive does it come back straight away.
Fix the top before you replace the sensor.

I wouldn't be replacing the sensors yet on the tests that have been done.

The man, we are defiantly going around in circles at the moment. Purely because i have nfi how they come to these results. It's back at the mechanics tomorrow (a different one) and i'll see what he says. I will pick his brain now that i know some knowledge.

Maztech, i'm not sure on that one. Since it was literally a week that it happened again. So i'm assuming if they were faulty, they would come back straight away. However, since nothing happened in that week we are un-certain when it came back. The mechanic should of cleared it then turned the car back on, then check it again. I will get him to do this tomorrow.

Overall, i've established that the "spit" is coming from oil leaking into the spark plugs. Once this is fixed, we will soon know more if that the sensors actually need replacing. If the leak was found in the first place, i would of saved money/ we wouldn't be talking about this.

Mechanic will hate me now, cause i'll be barking orders of what i want him to do

I thought i should update this just in case anyone else has this problem.

My car is now fixed and ready for the sydney road trip :P

So, in the end after replacing the coils, spark plugs/leads and fixing a oil leak and the fuel filter with it still spitting. We were having a laugh that it sounded like a helicopter at idle... Anyways, It ended up being the wire/plug that controls the O2 sensors. I'm sure TheMan can give us a insight of what this does.

But, its THIS THING!





So basically, my mechanic checked to see if still leaking oil (This didn't contribute to the problem either) after it was fixed. It was fine. So he thought it would be a fuel issue, and he planned to change the pump. However since he never actually has seen it in action of what it does, this was just another guess. So he was to order one in and i went on my merry way. As i was reversing out the car park, it did it! Drove it back into the shed and he checked the pressure of the fuel by removing some form of pipe where it connected to the engine. Fuel came flying out. He turned the car off, connected a guage, turned the car back on. Was reading around 50psi under throttle. He actually said it was a bit high. However, It was fine, therefore it wasnt a fuel pump problem. I left it with him to tinker.

I Gave him a list of things that i said that you guys have suggested on here. He told me that some of them wouldnt effect it (as we knew) but he was going to check it all anyways.

A few hours later he rang me up and told me to come in. He told me that he was checking the O2 sensors since it was throwing a code even though this doesn't produce the car to spit. The O2 sensors have been already replaced (by previous owner obviously) since they looked quite clean and new. As he was checking he checked out the plug, he apparently jiggled it and the car ran fine, let go and it went terrible (helicopter) again. He took it apart and sure enough the part was corroded/ the earth was broken. This was clearly making the car throw the O2 codes as well. A new part and its now running better than before! Such a simple thing that would of been fixed ages ago if a mechanic was to actually check things properly!
