The compression is all cylinders close to 150 and they all pass the leak down test it runs at higher rpm just won't idle
Expert:  Tim's Auto Repair replied 1 year ago.

ok,,t is missfiring[according to the codes

Expert:  Tim's Auto Repair replied 1 year ago.

the compression seems fine

Expert:  Tim's Auto Repair replied 1 year ago.

clean those plugs and replace the wires

Customer: replied 1 year ago.
I replaced the plugs and the wires are throwing good spark
Expert:  Tim's Auto Repair replied 1 year ago.

i understand they will have a good spark,

Expert:  Tim's Auto Repair replied 1 year ago.

but,,,

Expert:  Tim's Auto Repair replied 1 year ago.

these will jump a spark from te boots to the head,,and may not be noticable

Expert:  Tim's Auto Repair replied 1 year ago.

the odds are,they have never been replaced

Expert:  Tim's Auto Repair replied 1 year ago.

there is no good way to test those wires sense you can not duplicate the high voltage

Expert:  Tim's Auto Repair replied 1 year ago.

the compression seems fine,i would think you checked the valves while the head was off

Expert:  Tim's Auto Repair replied 1 year ago.

and,we are getting the ignition multi miss-fire codes

Expert:  Tim's Auto Repair replied 1 year ago.

thanks

Customer: replied 1 year ago.
If the cables were bad it won't pass the leak down test
Customer: replied 1 year ago.
The valves
Expert:  Tim's Auto Repair replied 1 year ago.

the valves,,that is correct,,thats why think it is an electrical ignition problem

replace the wires

thanks
