Ok, I have a really strange issue here. Every time I wash the car ( lots of water ) or if the car gets heavy rain while sitting at work (daily driver) it drops the 1-6 bank. Here's the funny part. I can start the car, it fires right up on both banks then after a couple minutes, the 1-6 bank will slowly drop off. The car has to be driven for a few miles, then the bank comes up. It's not spark as I checked with my timing light and all plugs are firing. It seems to be fuel gets cut off. I can pull the fuel pump relay on the 1-6, car sounds the same. I pull 7-12, car dies. Ok, It's fuel to 1-6 But, when the bank comes back, I can pull the relays and the 1-6 always sounds rough and not smooth compared to the 7-12. Is there anything on the coils including the little electronic plug in chip that would, if going bad control fuel to the 1-6 bank? When dry for a few days, I never have the issue unless water gets on the engine. All the connections are tight and clean. Maybe pointing me in a specific direction will turn up something.
