V bad Engine miss approx every 5 / 10 secs always.
Engine at idle in drive, much worse with a/c on. In park better. A/C off a lot better, but still occasional miss.
Changed coil block, plugs and plug wires twice.( With new ) no better.
I think all 4 cyclinders actually stop firing for a second, ( not just one ).

1. Defective spark plug
2. Inadequate spark/coil, defective spark plug wire.
3. Lack of compression

5. Faulty fuel injectors.
6. Insufficient fuel pressure.
7. Contaminated fuel.
