I pulled the plug and it looked good, than changed the plug wires to aftermarket with 1/4 of the ohm resistance of stock and it still would pop up going up hills, so I found a new coil off of gmpartsdirect.com for $30 if I remember correctly and the problem has never came up again been 10k miles. I made a post about it on hereSearch, Cylinder 5 misfire help might help
Lol i know what you mean, my second vehicle was a civic. I beat the living shit out of that car, it lived at red line for 200k . Only thing it needed was gas and an alternator.
