PLease help! Ive had it with this car!

Someone please tell me what the hell these codes are. We already replaced the coils! It runs like sh*t. Gets up to 2gs and it just craps out. Starts shaking and loses all power. After we replaced the coils this am it ran great for about 5 minutes then did the same freagin thing. We hooked the scan tool up to it and these are the codes we are getting:
P0300- random misfire detected
P0304- cylinder 4 misfire detected
P0301- cylinder 1 misfire detected

cylinder 2 was also misfiring before but for some reason fixed itself.

Now the cat is over heating

This is an 04 b6 a4 1.8t tip

maybe your popped another coil... i had 2 coipacks pop on me 10 minutes of eachother.

So you have already replaced all four ignition coils with 4 new and working ignition coils?

Original ignition coils tend to die out in close proximity to one another so it is always worthwhile to simply replace all of them at once.

id take the coils from cylinder 1 & 4, switch them with 3 & 2 and then scan for codes and see if misfires have switched as well. if so, return the 2 bad coils for some good ones.

Check you harness connectors for your packs. I had a bad one which was causing misfires and it drove like I blew a pack. It turned out it was the connectors not making full contact with the pack. The plastic piece inside the harness that guides the connectors was broken so there wasn't a good connection.

I had what i thought was two coilpacks go out on me.. swapped them out.. and the codes didnt change. So i swapped in new plugs.. all better! :)

[BoostedB6chica]

Thanks guys! Ill go get the other coil packs. And try that. Its weird because its throwing the SAME code with the brand new coil!

[A4Shizl]

Dumb questions but worth asking...

Did you clear the codes after the coil swap???

[BoostedB6chica]

yup. the only dumb ?s are the ones not asked

[KJIV]

maybe bad catalytic converter?

[diztek]

when my coil pack went bad, i drove home and my cat was glowing red.

Change plugs and clear the codes again.Try NGK's BKR7E gap them at .032 these are copper plugs one step colder than stock!
