car still misfiring after opti, coil, plugs, wires!!
i have a 96 z28. ive been having misfires for the last 5 months or so now. first i changed the opti, then i did the msd wires and coil. it is still misfiring but not nearly as bad. the performance shop i took it to say its now possibly a bent pushrod or valve springs. any ideas as to what else it could be???

I ended up fixing my miss by replacing a brand new O2 sensor. I bought 2 new O2 sensors from gmpartsdirect.com when I installed the random tech Y pipe, and it started miss firing after that. I ended up solving it by replacing the driver's side O2 again!
Have you replaced your O2s yet?
