Re: cylinder misfire

Probably bent a valve. Do a compression test.

Re: cylinder misfire

You used a comma (although not entirely correct), but still use no period?

It could be a bent valve. How much was the motor over revved on the botched shift?

Re: cylinder misfire

i would have guessed bent pushrods too, but i see you have replaced them...so I don't know then if it isnt a valve.

good luck!
