p0300,p0301,p0304 after spark plug change

[ipittydafoo]

Ok So I go do a spark plug change since I did a oil change today on my 02 A4 1.8t. 98k miles and they had original plugs. I replace with NGK BKR6E. After install I go for test drive and it started to sputter every time I floored it and the CEL starts flashing and it throws these codes. p0300,p0301 and p0304. I replace with the original I just took off and still same issue.
What the F going on here?? Did I jack up my Coil packs?? Did I have to wait for the car to be cold? It had been sitting for a couple hours when i did the change.

you probably have a couple coilpacks out. they dont like being bothereed and seem to crap out when yo change plugs. same thing happened to me as well. i changed my plugs then 2 of them failed the next day. you should always keep spares around

omg! What a picky lill b!tch this 1.8t. Can I still drive it carfully till I do get them? Also what's the sure way to test the coils?

[mike-2ptzero]

Move the coils to another cylinder and see if the misfire code moves with it.

ahh....ok will try that.

def coil packs... has happened to me twice with 2 different 1.8T's...

change the spark plugs and the coil packs go... now i do both at the same time =p

i agree i was on my original coilpacks and changed my plugs and all 4 failed within 2 days, luckily i had 4 spares in the trunk.

i've changed my plugs 3 times already and my R coils are still strong. (20k Miles)

^yeah same here, just gotta change plugs first thing in the morning when the engine's cold

My coils crapped out the next morning as well... But yes, this car is a picky Bit*h/
