Re: Need help!!!

It might be that not all cylinders are firing. Did you recently change the spark plugs?

Re: Need help!!!

I wouldn't do it just yet. Did you check to see if you have any error codes?

I believe it is:
1251 Fuel Injector 1 (or group 1 for DME 1.3, cylinders 1, 3, 5)

Look at the check engine light (flashes once pause, then twice pause, then 5 times then 1 time

okay great! I will order that and hopefully it helps! I found out that one of the crankcase hoses attached to intake boot was disconnected. Hoping that these few things will help. Thank you for your help!

yes. but you probably have a coil pack problem. 214K is a long time for 6 coil packs to be firing regularly. i would look at those. My E90 had a sever misfire a couple months ago, 54K miles and 2 coil packs were shot....
