E46 Engine hesitating dropping revs and loss of torq

[Aziz]

My E46 323i with m52 engine has started to hesitate dropping revs and loosing low down torq.
This doesn't happen all the time I think its a intermitant fault no engine management light have come on

Anyone come across a similar problem or point me to which direction I should look?

Got an E46 my self, not had this problem though. Maybe ask on www.e46fanatics.com

Well I think I may have found the answer just bought some Dielectric grease to put on the spark plugs as I changed no 6 coil pack.

\if it not that then I've got alot of investigationg to do????

These are the parts that a guy has changed with the same problem as my car

Well, I have been loosing power and smoothness. I changed the o2 sensor power came back then disappeared after about 2 weeks.

I change the spark plugs power came back and disappeared after 2 weeks

I changed Spark Plug boots power came back and disappeared again after 2 weeks.

I changed out the MAF sensor and power disappeared after about 1 week.

I change Intake Cam sensor same thing power came back lasted about 1 week or so... same for the exhaust.

No check engine light, but it's clear to me that the power is gone.

The dyno now shows me that I am running rich which explains the why I am loosing power.

Just don't know why.
