I have a 1997 Proton Persona which has many Mitsubishi parts: the engine is the Mitsubishi 4G15 12 valve 1468 cc. I think it's all very similar to a Colt. Suddenly the engine has started to severely misfire when I accelerate. I have _advanced_ the distributor by about 5 degrees which has reduced the effect, so now the car is driveable, but now the engine pinks. (Is that a British English word? I mean I get a high pitched tapping when I accelerate uphill in a high gear.) What has gone wrong?
Timing belt was changed about a year ago, when the head was planed after a head gasket failure; all has been OK till this week
