I have changed out all the plug wires, all (amazing, there are 12 of them
) sparkplugs (looks like one of them was way old!), rotors, caps, etc. I do not drive a lot and tried system cleaner once. My "newest" idea to buy way premium gas (ARAL 102), as it supposedly has cleaners in it. Only had two fillups so far, so who knows...
No codes, would be to easy...
After changing the coils it seem to have gone away for a while and I was hoping to finally have nailed it. No such luck.
Thankx for your ideas.
