Engine misfire, runs rough and ticking noise

What is your question?

S10 parked for 2 years, started the engine monthly. Last week engine cranked slow and backfire during crank a couple of time. After engine started it was running rough, missing one cylinder, gave gas to bring RPM up and a ticking noise developed. Noise get louder as RPM goes up. Engine Service Light ON, Tech II scaner read code as "Engine Multiple Misfires" Did the misfire caused a lifter rod to bend?
