The car is a Saturn 2001 SL2. Engine is 1.9L DOHC. The timing chain was replaced and now it drives like it’s missing. The computer code is P0301 which is a cylinder #1 misfire. Replacing plugs and wires didn’t help so the timing has to be off. It runs like crap but is it safe to drive? Will it cause damage? And how much to fix? Thanks.

Number 1 is the frontmost cylinder. Front being the end with the belt.
