Hi folks,
My VP runs fine when I first start in the morning when it is still cold. But once it gets to operating temperature, it starts to run really rough when I accelerate. It coughs and splutters generally lacks power when I accelerate.
So far I have replaced the coil base and packs, spark plugs, leads and the oxygen sensor but the problem still remains. My son and I did the the self computer diagnostics with a paper clip as described in the How To and the code comes up as 12 every time (no faults by the codes sheet).
I'm wondering if anyone has any idea of what might be causing this. Any suggestion would be greatfully welcomed. We are at a loss as to what may be the problem.
All the best
