1984 GMC 3500 2wd 350 engine

Last year, I had the timing chain changed along with cap, rotor, plugs, wires. truck was back firing after I turned off engine. A timing adjustment fixed that.

Truck is now at mechanic.
When driving, truck will misfire for like 2 seconds and then back to normal.

What things can cause misfiring?

Thanks
