Okay, very strange thing happening at the moment, just going to see if anyone has any ideas, as i am running out of them...
car has been misfiring for a little while, cleaned the AFMs, gotten new fuel filter, new o2 sensors, new set of coil packs, new spark plugs, tried a mates igniter pack...so far nothing has fixed it...
i will start the car in the morning, let it warm up, then drive on my way to work, it will boost and drive fine all the way to 7000rpm hapily...then once it gets hotter or i have been driving it for about 10-15mins, it will start to cough and splutter...starting at like 3000rpm all the way up, if i drive under this it seems fine, if i rev into the spluttering, it will blow my IGN fuse under the bonnet and the car will shutdown...
we have tried all of the above, extra grounding on the engine, sorta out of ideas at the moment...anyone got some suggestions on what might be causing this???
