just looking for some insight, I've done some searching and reading to see if i can come up with a solution. My 03 has 27k miles and a 2.2 Kb @17psi and i haven't had any issues till recently. The car started to miss a bit throughout the rpm range so i changed the plugs and went with the Tr6 like i had before. the miss went away for about 50 miles or so then came back. any help will be appreciated. perhaps coil pack and is there any way to know for sure without buying all new ones? im going to clean the maf connector today and see where that gets me.
