How To Disassemble My Distributor? Options

[j0ch0a94ST]

Hey guys I've had an issue with my 94 ST running rough until it reaches operating temps ever since I washed the motor. I pulled the plugs and replaced the plugs. There was no water in the chambers. I have pulled the dizzy cap off and there was some moisture inside. I have dried out the cap and sanded down the terminals inside. I have currently pulled the distributor out of the car. So how do I disassemble it to look for trapped water? I've pulled out the 4 main screws but the plastic covers are blocked from coming off by the rotor button. There isn't a screw or anything holding the rotor cap on but it seems stuck. They do come off right? I just don't want to break anything. Anyone with any experience with this please help.

Thanks

its a long shot but maybe once the engine is in closed loop, which happens when the engine is warm the o2 is reading either a lean or rich mixture. If you could, when you have the engine warmed up unplug the o2 sensor so the computer ignores the o2 signal and just gets readings from other sensors. Just an idea.
