Please help
I have 83 280ZXT engine surges,running reach and backfires at random,all plugs is black.

-At the cap I have a weak sparks from all plug wires and same as at the plugs,barely can see the sparks.
Spark from the coil is orange but good spark and you can hear it snaps.
-Testing with different cap and rotor.
-Testing with good coil wire and plug wire.
-Testing with new ignition coil.
-Autozone test the alternator and good.
.....And still have a weak sparks.
What else could causing the weak sparks?
Thanks

 

I'm not sure if the turbos have an Ignition module, but I know the non-turbos do. The ignition module is a little black next to the distributor. that is also responsible for giving you a spark. I had a similar problem with it. and changed the ignition module and now everything is fine. good luck and hope another person who is familiar with turbos can respond
Z you later.
