HELP - not firing on all cylinders.

Hi,
I really hope someone can help me with my problem. I have a 2001 BMW 535i E39. It's not running on all cylinders. I've changed the spark plugs, o2 sensors, alternator (which needed changing anyway) and I know the coils work but it hasn't made any difference.
I really don't want to take it to BMW people because around here they charge 89 an hour for labour
If anyone could give me any advice, it would be greatly appreciated.
Thank You

When you start the car do you experience a rough idle or does it shut down immediately?

In situations like this we need to know what the fault codes are.

I bought the car like this - real cheap as I've owned a 98' model before. Absolutely loved it and I want to get this sorted and like to keep it for quite some time.
Previous owner has a stack of paperwork of services done to the car for whatever it needed but reading through the paperwork has nothing relating to the current issue.

I'd type /misfire f3 in the bestlinks to see what the common causes of the misfire might be:

The main issue that there is no spark to the one set of 4 plugs of the 8. I've put new spark plugs in and tested the coils and I still get no spark ???

It's still a misfire.

Are you sure that thread, which covers at least a dozen or more common causes of misfires, doesn't have what you need?

For example, did you swap the coils when you tested them?

If you're quite sure that the comprehensive misfire thread doesn't have what you need, then I'd run a title-only e39-only search for "no spark", as is suggested in the "how to find stuff" sticky ...

You certainly have an unusual problem mainly because you have a misfire and no codes-a misfire will always generate a code. I suppose it's time to guess but I also hope that one of the V8 guys chime in to help.

i think you should check fuses first-the ones above the glove box, those in the trunk and those in the e-box under the right side cabin air filter. I don't know if you have any water leaks in the right side foot well but there is a fuse box under the right side front floor that supplies electricity to mostly all the electric circuits in the car. If there is a leak there that is not taken care of, the water will find its way into the fuse box and cause corrosion that will have dire effects on the car's electrics. You need to unbolt the seat, pull up the door sill plate, and pull up the carpet and insulation to access the fuse box.

I have 2 other thoughts. One is that someone has messed with your check engine light so I wonder if it illuminates when the ignition is turned on but then again, you say that your scanner pulls no codes. The other is a DME problem. I know that the US V8s have a problem with the thermostat wire wicking coolant up into the main DME plug causing DME damage. You may want to pull that plug and see if there is coolant there.

Please realize that these are all guesses since you have no fault codes. I am also very familiar with the I6 engines but not so much with the V8s.

Good luck.

Verify that the ground/earth strap in the spark plug chamber on that bank is tight.

That's gotta be the most common lean condition misfire code out there.

If you read the thread I pointed you to, you'll have the solution to your problem already outlined, in gory detail (I know, because I had the same error, numerous times, and solved it every time using that same information).

Sorry this might sound a bit stupid but what do you mean by 'bestlinks'? it's the first time I've used this website and I've got no clue about where to find the thread you mentioned.

The answer to that question is cleverly hidden on the very first thread in the forum:
Titled: Sticky How To Easily Find Information on Your E39 Topic Before Posting a New Thread, by Fudman

Read that thread. Every single post. It will only take you a few minutes (less time than I've spent already on this thread, by the way)...
It will explain everything (not to mention my signature below does also, and so does every thread you can imagine looking at).

Such a great post Bluebee. I guess we both wasted some time on this thread. Misfire and no codes indeed
