Spark problem!
 
Hey guys,

I am having a intermittent spark problem. When I turn the engine over I get a intermittent spark...sometimes the first revolution...sometimes the 4th....its just random. I have two DME's the first was the one that came with the car and I bought the second to see if the first dme was bad. The first dme gives me more spark than the 2nd one. I don't know if either one is good.

Here is what I have done so far:
1. new speed and ref. sensors (gapped them but still no tach bounce)
2. new dme relay
3. new dist. cap, rotor, plugs
4. checked coil
5. checked ignition switch at #4 terminal on DME plug and ground (10.5 V)
6.

When I turn the engine over I can hear the ignition relay clicking alot...is this normal? Any ideas on what might be causing the spark problem?

Wiggle the plugs around for the speed and reference sensors while cranking it over.
