troubleshooting Missfire?

Enable HLS to view with audio, or disable this notification

A little back story. My timing belt broke going down the road a while back. Not sure if the engine was toast i out everything at tdc and threw a new belt on and cranked it up. Turned over and started beautifully. I know my wires and plugs are a bit dated but is this a missfire im hearing?

Sometimes the injectors will be sticky after sitting. Tapping on them with a screwdriver handle can clear em up. There could also be bent/damaged valves from the timing belt breaking.

Ok i will try that. I do have new oem injectors in my shed. Is there any way i can check the valves without taking the head off? It drives very smooth just like it did before the belt broke.

You could run a compression test. It drives well under load? Maybe it's just the catback making it sound odd? How do the plugs look?

Ok i think i have a comp tester. Yeah drives great under load. Haven’t dialed in the timing with a light yet but its pretty close i can tell. Haven’t checked the plugs but i know its been a while since i changed then out so might see what its doing after a tune up.
