Been trying to fix this issue for a while. Heres what I have:
Misfiring on cylinders 1 and 6. When I start the engine, the car runs perfectly, no misfires, nothing at all. I drive for about 5 minutes at ~70km/h, and the car starts shaking. Read the codes, P0301, P0306.
The car use to misfire on cylinders 5 and 6, but 5 has since 'moved' to cylinder 1.
Also, when going ~80km/h, if I open the throttle, say, half way, the car shakes violently, but any more or any less than that, the car just shakes slightly.
Recently changed: Plugs, plug wires, coil pack, EGR valve, cleaned IAC and intake. Cleaned MAF sensor.
Took plug and wire from cylinder 4, switched them to cylinder 6, same thing happened.
Shutting the car down, and starting it 2 minutes later fixes it, until I drive for around 5 minutes again.
Any ideas at all?
