It will be a guessing game regardless.. the only difference is they take an educated guess at the issue.

the car looks to be in good shape, just needs some tlc, good luck with it

Have you checked your fuel pressure regulator? If it goes bad fuel can pass through the valve and actually be sucked into the intake manifold through the vacuum hose going to it. Pull the vacuum line off the regulator and see if there is fuel present, there shouldn't be.

and if i take it to a shop and let them do diagnostics will their test be able to pull exactly what it is
or is it still a guessing game regardless...

just like a doctor, a technician will be requiring additional tests to check the systems are operational.

as for the descriptions, it sounds as if you are not getting spark to the business end of the plug that is *not* getting fouled. the others are running super rich, as evident by the heavy carbon described.

i believe that i had mentioned the fpr, which is definately a possibility. check the vacuum line to it. it should be dry. if there is any fuel in the nipple, then you need an fpr.


and change the oil, when done...

hold on armando. may as well check everything first. Also you're using some lingo that I've never heard of. lambda code is O2 sensors here in the states. and productivity would be called a fuel trim test. Rampage, i know on OBDII cars you can check the fuel trim with a handheld reader. i dont know about OBDI cars such as yours. Can any of the older guys (DF, ZeGerman, Horn, any of the Chads) comment?

rampage you could take it to an independent BMW specialist for a diagnosis but it could be hit or miss. and thats assuming you have the money. we know you have spark. lets try and make sure you're running on all cyl first by checking off fuel and air.

the best way to check for proper spark is to use a spark tester. it replicates the conditions in which the coil will experience when trying to spark in the combustion chamber.

simply holding a spark plug against a block/head @ atmospheric pressure will do nothing of this sort.

you have to look at spark as being a little lazy. it wants the least resistance to ground. if it finds another way other than through the sombustion chamber, then hc will be off the charts and will run rough.

and also not fould the plug with carbon, but rather wash it very clean with fuel.


hope this clarifies some things.



as for checking the o2, the best thing is to use a power graphing meter so you can see the signal. expensive, yes, but soooo much more accurate than a dvom. even a fluke88, which is quite pricey.


ya wanna play, ya gotta pay. and with the level of "diy'ing" going up as cars have become more sophisticated, specialty tools are going to be the norm.

of course this is also why some car clubs have pooled their resources and purchased big ticket items for use with their members.


just something to think about,,,,

going to a dealer is usually not worth the extra money. if you can find a reputable indy mechanic (preferably one who specializes in BMWs) then he should be fine. Just be prepared for a long list of expensive parts. You may get lucky and it may be one cheap sensor or a few new injectors or something but i wouldnt bet on that.

so you've given up on trying to self-diagnose?

Well the shop hasn't found anything
The codes aren't pointing them to any answers
They don't even know if it's electrical or mechanical or both
I'm stumped on what I should do next
I don't know how far I should take this
HELP!
