"If coil packs have more than 30K on them, replace them as a failure is imminent."
I replaced mine along with plugs, fuel filter and AOS this weekend and I was impressed by their condition, it was bad. I think only one of the six coilpacks that did not have cracks and large cracks on them in several places. Funny thing was the car was running pretty good except for rough idle (probably vacuum leak).
So, I have a question about how smart our ECU's are. Do the ECU's need to readjust to the addition of new plugs and coilpacks. My old plugs were only a year old, but the coilpacks were the original (90K). The car is running fine now, but seems like it is not quite as quick (quite subjective) as it was before swapping out parts this weekend. That is why I am wondering if the ECU is adapting. BTW, if its not clear already, I know just enough about this stuff to be dangerous....
