My 1.8 VVT has just recently been lacking power and hesitating. I'm planting my foot to the metal but m speed decreases (motorway driving). Round town it's still evident but not to the same degree.

I run on LPG (done about 25k so far) without any problems. The problem only seems to be happening when running on gas. If I switch to petrol, it goes away.

The EML has come on and that's giving me 0301 - 0304 (all 4 cylinder misfires detected). Also a 0170 fuel correction dysfunction (assume its related to the misfiring).

Im changing the LPG fuel filter and plugs tomorrow. Fingers will then be crossed to see if it works....if not, I assume it could be a coil pack failure...

Any other suggestions?
