Acura TSX / P0301 (Misfire Cylinder 1 Code) = Bad Coil!

I was just driving along the other day minding my own business, when I hit a bump and suddenly my car went into limp mode and ran like dogshit. Severe power loss, rough idle, just garbage, flashing check engine light plus emissions warning. I got the code read and it was "misfire cylinder 1". I tried a new spark plug first, didn't help, so next was the coil, and that solved it for me. Takes 5 minutes to replace and all you need is a 10mm socket.

Hope this helps someone who may be in a similar situation. My car is a 2006 Acura TSX 6 speed manual with 113k miles.

    What are you going to do in 10 years when all the integras, RSXs, and TSXs are crushed cubes in the junkyards?

      @Red88Rex ha, I was just making a fun comment on how you've been owning so many of the Integra lineage of cars and they won't last forever!

      That’s a weird question. I don’t even know what to say. I just tried to post something to help others
