Serious Engine Problem Help!

[ProJect_*A4*]

i was driving on the freeway for about 20 min. i was getting of on an exit and pulled a u-turn kinda quickly, soon as i started going straight again my check engine light started flashing!! and then all of a sudden my engine started to shake obnoxiously! I still get the same amount of boost but i accelerate NO WHERE NEAR to regular. i killed the engine and unplugged the + and - on my battery. sat there for a minute and connected the battery back up... started the car, no check engine light but the engine still shakes. soon as i started driving again check engine went back on...

I dont have vag com and i need this fixed asap, cuz i have college...

PLZ HLP GUYS... i have no clue what the problem is...

could it be the coil packs?

i have a feeling one of my cyllinders went out.

info plz plz

i think im over-reacting... im pretty sure its a bad ignition coil..

im gonna go see if one of em went bad... update comin in a min..

[B6driver]

sounds like a classic coilpack blow out.. by "shake" do you mean chug like a subaru?

[B6480Avant]

lol that was dramatic sounds like a cp

[ggar015]

Coil Pack... Try to disconnect one at the time. If lets say you unplug the first one and nothins happens, then that would be your bad coilpack (or more)

better replace them coil packs :)

audiprotieen thats what i did last night... im pretty sure i know which one is the faulty one.

anothe quick question. could it have anything to do with a bad spark plug?

[ProJect_*A4*]

anybody know where i can get ignition coils on a sunday in the seattle area? specifcally up north near lynwood?!

lol...doubt any good answers will sprout..

[downhillracer]

a bad spark plug can do it but they don't fail often...its probably a coil pack

well its my 3rd cylinder thats misfiring so im gonna grab a spark plug before i spend more on a cp... if that doesnt fix it then theres nothing else it can be but the cp.


quick question, how much can you drive in my situation with only 3 properly workin cylinders..? i know i shouldnt but i had to get home and im guessing i couldve thrown off my timing and retarted my system by driving with that bad cp... am i wrong?

Its a coilpack, #3 is 99% of the time the first one to go as it runs the hottest and leanest. Dont waste your time with the plug, and for that matter if you want to prove to yourself its the coilpack, swap it with another cylinder and the misfire will follow

ok. thanks. well is it a good idea to change all coil packs right now? along with all new spark plugs?

i dont know if the previous owner swapped either throughout his ownership but i just cracked 100k miles and dont want to be running old plugs/cp's.

plus i have a rough idle so def. new plugs...

as for the cp's??? any1?

No need, but wouldnt hurt. Eventually they will go out sooner or later (old ones). So u can change them all and keep old ones as a spare (just i ncase) or keep 1 or 2 of new ones as a spare.

kk, sounds good.

spark plug recomendations?

im thinking NGK BKR6E's or the 7E's..
