Replaced spark plugs and coil packs on my 05 545i, now when i started the car, she barely runs, idles really rough and check engine light is on with codes P0300, P0301, P0306, P0303, P0307 AND P0300

ANY HELP IS GREATLY APPRECIATED

0300 - Is engine misfire code. P0301,P0302,P0303 and so on is your cylinder numbers. Seems that all your Cylinders are misfiring I would check the coil make sure you have the timing correct, also make sure you have correct pugs and ignition coil! Do not drive the car!!!!!!!!!!!

Sounds like you screwed up the coil order.....

double checked part numbers and everything that im coming up with is correct...Bosch 0 221 504 464-076/00124 coil packs, and NGK BKR6EQUP (3199) spark plugs


*sigh*

Did this problem existed PRIOR to the plugs and coil packs replacement?
What prompted you to replace lugs and coil packs? Did you replace ALL of the coil packs?

Like a previous post stated - verify the coil order. Also verify the coil packs are connected firmly to the spark plugs.

how do I check the coil order? What is the correct order? I havent read anything about it the DIY

So wait... when you changed the plugs and coils, you just randomly put them in? That is no doubt your problem. Each has its own place... its own order.

I don't want this to sound rude, and please don't take it that way, but have you changed plugs and coils before? I wouldn't start with a 545 unless I knew damn well what I was doing!

Im not taking it the wrong way, trust me when I read that earlier I already felt like an idiot. It has been many years since replacing them. How do I find out the order?

I wish I knew... I am sure someone will chime in here... I always do one at a time. There has to be a tool or a way. Good luck!
