Need some misfire help background info:
i was taking a potential buyer for my car on a ride and he asked my to punch it so i did. car ran good and pulled fine, i coasted for a while and took an exit. i got about two miles down the road and came to a stop sign. at the stop sign the car really started to miss bad at idle and stumbles from a take off. at idle you can really smell unburnt gas. (cam only car)
i replaced all of my plugs and wires and it still is missing bad. also it still smells very rich at idle. i have no clue what it could be, mabey a bad coil or something?
also the car is throwing no codes and on the live dash the spark jumps around.
any help or input is greatly appreciated.

ok update all coils are fireing and still the car runs like it has a huge misfire, i went over all plugs and wires and everything is good. forgot to say in my first post that the car also has a clank that gets louder with rpm.
i drove the car around the block and it feels like it has no power at all. took of my oil filter and cut it open, no metal at all in filter or oil. i decided to remove the passanger valve cover because that is the side all the noise is coming from, all rockers were ok and no pushrods are bent.
now im thinking it could be a bent valve, im not sure how a car would run with a bent valve though. im done messing with it today though.
i appreciate any help or input from you guys.
