It starts. Runs like crap. Seems like it's missing at idle (or running on one cylinder), shaking and loud. On high rmp (driving) sounds like a freaking rod is about to go. But I think this is 'pinging'. I don't think its mechanical because the noise stops as I let off the rpms and the engine still feels fine.

Here's what I know. Spark is blue. If I remove the #1 plug wire, engine is the same. #2 wire engine is same. #3 wire, engine dies. (by the way I get spark on all wires).

I replaced the cap and rotor, not much difference.

Disconnected the AMM, car still runs the same.

I checked the AMM, hot wire in tact. How do test it's ohms? Can't find a mention of it in the manual??
