My Ride: 330ci convertible

Just like to share my experience with coils with you.
Last week my car started to run on five cylinders one morning.

To through a red herring into the mix I'd just filled up with petrol the night before and travelled 1 km home. To add further to the confusion a sample of fuel from the tank was yellow, yet the day before when I fuelled up the lawn mower fuel was red. I later found out they had stopped putting red dye into the petrol some time ago.

Any way after checking the coils and plugs visualy with no signs of shorting or tracking, although 5 coils were Bremis and one was a Bosch, I started pulling the connections to try to find one that made no differance to the idle when disconnected. I thought it a bit strange at the time that I had to repeat this a few times as some of the coils appeared to make more of a difference to the idle than others.

Eventually I found one that made no contribution to the idle and verified it by changing out with another coil. I replaced it with a new Bosch and all was fine.

After thinking about this for a while I replaced all the other coils with new Bosch ones. The car was much better off the line and also ran smoother.
At first I thought I might be imagining this, it reminded be of an add we have here of a rough looking couple in bed, the guy pops a Eclipse Mint into his mouth and offers one to the girl. In the next shot he is dressed in a white shirt and navey blazer and the girl has had her hair done, feathers in her hair and dressed like a shiow girl. He looks at her and says "You look fresher" she replies " Don't be rediculous".

Anyway I got the other half to drive for a while and she also thought the car was much smoother.

And I thought coils either worked or they didn't.
