I will have to move the new coil pack that is on that cylider to another and see if i got a defective one or if it is something else. Im still trying to put my finger on it on whats causing it to misfire. I hope i can figure it out this weekend. I have tried the fuel injector cleaner and it doesnt seem to work. Maybe use it more often like every other fill up and see what happens?

Read my previous posts. You will need to take it to a shop that has the injector cleaning machines. Much more effective than the bottle cleaner. If that doesn't clear up my guess would be replace the injector or a valve problem as someone else stated.

I agree spearchucker. You're right. The milky stuff almost has to be water condensation. It happens here in the mid-west too when you make lots of short trips. That's the hardest thing you can do to your car... I was just trying to find out what the "clumping" thing is.

I always use valvolene, but I don't use the synth. It cost too much, so I have only limited experience with it. All I see when I change the oil is black nasty smellin' liquid. I have, and have had several cars approaching 200k miles, and the ones I used valvolene in performed the best with the least chatter from the valve train.

If the moisture seems really bad check the PCV valve and hose.
