Help me diagnose my miss over 4500rpm.

I changed the fuel pump, the plug wires, the intake gaskets and I messed with the timing. That all took place after the miss started. Do you wreck anything if you set the gap with a regular feeler gauge? Cause I did set it with a regular feeler gauge. That was after the problem started too.

yes you can sometimes mess up the pickup coil with a steel feeler it is recommend to use brass . the last pickup I put in was 19 bucks and fairly easy to do .
