Thanks for the advice everyone.
I have had a play this afternoon, and have made some semi progress. This is the state of play atm:
- changed fuel pump
- changed coil pack (s)
- checked and cleaned all the earths
- checked fuse box
The car will now run at idle fine, however as soon as I try to apply any gas the car hits 2.5k, and dies. This leads me to believe that the problem is not with either the HT leads or the spark plugs, as I would have expected the idle to be lumpy and this is not the case. I will upload a video of the issue at some point.
Well done. From moving backwards we are on a forward journey.
Video was very helpful.
Looks like its loosing quite an important sensor.
There is few that are affected by speed or the amount of air flowing.
But the only one I can thing of that would cause such a catastrophic failure would be the crank position sensor. Never seen one fail like that. They normally fail over time as they warm up. But a quick Google search picked up this.
