early VR6 petrol smell from exhaust during warm up period

[Marky 0]

Hi, its a 94 Golf, an OBD1 model, I replaced the coil pack a couple of weeks ago, but for the past few months I've always noticed the smell of petrol until the engine has got to operating temperature, so looks like a rich mixture? The engine doesn't stall, it runs fine just strong smell of petrol. There is no petrol smell if you do a warm start. The lamda sensor was replaced in December. Is the best bet to get someone to do engine diagnostics on it?

Also, is there an engine management light on the dash? The instruction book doesn't show one in the warning lamps section, how would you know if there is an ecu problem?

Had a look, turns out it has only been running on 5 cylinders!!! Replaced the blacked up spark plug but now its misfiring on that cylinder so I'm going to get the coil pack checked.

They are very picky about HT leads, wait till its dark, start the engine and mist the leads and coilpack with water and look for arching, could be just a cracked lead
