I am having an intermittent runs like crap situation, that is kind of weirding me out.

Ever once in a while (usually in humid situations), the car will run like crap (like the MAF is unplugged and you can only keep it alive with throttle). Running super rich (I can smell it). Then it clears up after a 5 retires and runs like it never happened.

I haven't driven the car in a while just trying to get the situation happening again. Today it is happening. Squirted the CAS/Ignition Coil/Power Transistor with water to see if I could get an arching situation, but no luck. Started pulling plug wires at the spark plugs. Have great spark on 2/4 but weak spark on 1/3. Aren't our coils supposed to be 1/4 and 2/3? This is the part that is messing with me and I don't know where to go from here. Help!?!

I see I never posted a resolution to this. It ended up that my MAF died. I replaced it with a 3g eclipse gts maf (482) and the wiring connector that Iceman makes click and it fired right up and has been running great all this time.
