Engine Stalls at idle, next to no acceleration in gear

I just bought an 81 corvette. I was planning on getting it tuned when it suddenly started to stall at idle. The next day I aded a gas treatment and within minutes if has almost no accereration in gear. It revs fine in nuetral or park.

Load issue, so I'd say Plugs/wire/distributor. What is there age/condition? Beyond that that only reason would happen after a fuel treatment is fuel filter is clogged.

Check ignition timing to see if cam has jumped a tooth.
