I'm bringing this back from the dead. I was talking to some guys last nite about my car running like crap and my spark plug being very fouled out and coated in a black deposit. At first I was thinking it was an oil leak of soomesort like someone mentioned above a bad valve seal or bad piston rings. Well this morning I went and started the car for the first time in four days and fired right up. I let it idle for a few minutes and turned it off, pulled the plug. So mind you I swapped the plug last friday with one from another cylinder, drove it saturday and havnt ran it till today. When I pulled the plug it wasn't black but it was wet not sticky and smelled real bad like gas. I'm prolly gunna still swap the valve seals but I'm leaning more towards the injector being stuck open. So I'm gunna get some new o rings and some seafoam and swap the injector with another one and see if the missfire moves to another cylinder. If it does problem solved and ill run the seafoam through it and see if it helps. If not well then it is an oil leak. I also did a compression test here are the numbers:

#1- 145
#3- 145
#5- 142
#2- 132
#4- 133
#6- 145

For some reason #2 and 4 are the lowest numbers. To refresh the car has 145000 miles and the missfire is on cylinder number 4. I don't think those are bed numbers for such high miles. So what do you guys think?
