Hi
I recently bought a 1993 Vauxhall Carlton 2 litre 8 valve at auction and it started and drove very well. Then one weekend, i left the car running and after about 10 minutes of idling, i noticed it starting to idle very rough. The car would shake and revs would drop then go upto
2k revs before coming down again. This would continue along with a distinct smell of rotten eggs (excess unburnt fuel?).I thought nothing of it at the time and it sat in my driveway for a week. On trying to start the car the next week, it turned over and over and did not fire up. I did it until the battery went dead. On connecting jump leads i managed to get the car started after about 5 minutes of turning over and pumping the accelerator. Eventually it did catch.
When started it misfires badly, occasionally stalls. Taking it for a drive, sometimes there is no power (foot to the floor - car struggling under 2k revs), sometimes there is full power.
If i turn ignition off and start again when hot, it has trouble starting again and it will turn and turn until eventually catching.
Help! It was running fine a couple of weeks ago!
Having read previous threads, am i correct in thinking it could be the ignition system which is at fault - HT leads, distributor, plugs etc or could it be a sensor of some sort?
Any help would be much appreciated.
Thanks
Steve
