Did you run the codes yet?

Doing a little spell check and proper use of punctuation/capital letters also makes your posts easier to read and understand. Doesn't have to read like a novel, it's just how your wrote it, it's hard on the eyes.

Holy understatement of the year. I normally just chuckle at bad spelling/grammer but this post takes the cake.

i would do a compression test and see where your at. if your low on compression then that letting oil get past the rings and kill the plug. also does your car smoke at idle then clear up went you give it gas? if so this is a clear sign of oil seeping by your valve guide seals and if its really bad this will also kill your plug. if all that turns out to be good check your fuel pressure at idle it should be around 35psi. if that passes the test check your coil voltage not the power wire but the voltage going to the coil post. and also check the cap rotor for wear and build-up. hope this is some help.
