PINGING & CLATTERING

1995 Volvo 940

I have a 1995 Volvo 940 that has pinging and clattering on acceleration. It also misses at idle occasionally and will fall dead at times. I feel that the timing is very advanced and will not retart. I think it is so advanced that at idle it causes the miss. It could be two separate problems. I have tried a different knock sensor to no avail. I put a timing light on and the mark is way to the left of the timing marks looking at the front of the engine. What should I check out next? Thanks
