29CD-cylinder 1 misfire
2ABC-tmap? or tune? charge pipe?
2F6C-golf tee
2C77-02 sensor?

literally just happened this morning, driving normally then my car sounds really rough. ive had misfires before, but only misfiring due to foul plugs (misfires at wot). Its running rough and you can feel the car shake. Restarting does not help,it feels misfires on start up. CEL is is also on.

now, i think plugs are okay maybe 15k miles since last change. What would cause a misfire on start up?

i dont see injector codes, but am i dealing with normal misfiring issues? (coil/plugs injector) or is there something else wrong. it was running perfectly fine, i was cruising when this happened.

Switch out the coil from cylinder 1 to 2, and see if the missfire travels to cylinder 2 now. Easy way to determine a bad coil.

ok, so i swapped coilpack and it did follow 29d0, but it also still has a misfire on cylinder 1? should i clear codes everytime? or is cylinder one still misfiring also?

clear codes and see if you are still getting a missfire on 1. if you are...it isn't coils...did you say you are missfiring on 2 now? if so I'd replace that coil that you switched. try switching the plug from1 to 3 as well to try to eliminate plugs
