e39 Misfire issue with 6 codes...

Hey guys,

I've been searching for a few days trying to decide what is going on so my apologies if I overlooked a thread for this but here is what is going on.

2002 530i

Loss of engine power and stalling
Misfire and rough idle
Idles low with difficulty bringing up the rpms
engine dies when I step on the accelerator when idling
terrible gas mileage
Check engine light on

Here are my codes:

P0313 x2 (1 is Pending) - misfire detected with low fuel
P1343 - Misfire cylinder 1 with fuel cut off
P1620 - MAP Cooling control circuit signal high
P0174 - fuel mixture too lean
P0102 Pending - MAF circuit low input
P1344 Pending - Misfire during start cylinder 2

I've cleaned the MAF and checked/cleaned the spade connections on my fuel pump. It seems like the engine is being starved for fuel but let me know if I'm missing something. Any advice about what this might be would be fantastic!

UPDATE

I decided to check out the ICV while pulling the DISA and clean it. While doing so, I noticed a rather large crack in the intake boot. Could this be the cause of my issues? Regardless, I'm replacing the o-ring on the DISA and cleaning the ICV. I'm thinking about doing the valve cover gasket as well since I'm leaking oil at a decent rate.

How old is the fuel filter? If original, replace it. BMW now acknowledges a 100k service interval.

Sometimes, cleaning the MAF works; sometimes, it doesn't.

I checked the fuel filter, it looked pretty clean to me. A couple specs but nothing that would clog anything. I tried cleaning the MAF but that didn't help any either.

I had the same problem ... btw. And almost the exact same codes. See my solution in the misfire threads.

To find them, I'd suggest going to the bestlinks and searching for the 'misfire' thread which will point you to the solution.

Just removed the disa. It seems fine except The rubber seal ring was flush with the housing. Is this normal? I can upload a pic if that helps.

Yes the big crack in the maf boot will cause your problems.. Replace it. While your @ it clean & replace the gaskets on the tb. You'll see a difference.

Everything said above is listed in these threads ... which I get the same way you would ...

I go to the bestlinks ... and then I do a /vacuum or /disa or /misfire and they all have what is said above.

For example, on the DISA o-ring question:
- Where to get a proper DISA valve repair kit (1) & how some jury-rig 'repair' a rattling DISA unit (1) (2) (3) & how the DISA valve operates (0) (1) (2) (3) (4) & how to test DISA operation (0) (1) (2) (3) (4) & a simple DIY to install an M54 DISA (1) & a nice DISA autopsy (1) (2) & a great DISA group buy (1) & how the disa valve o-ring fails (1) (2) & how it can reputedly cause all sorts of cold-engine rough idle problems (1) (2) & where to get just the DISA valve o-ring (1) & why you want to check the DISA at 100K miles or whenever the airbox is removed (1) (2) & why the DIfferenzierte SAuganlage ("Differential Air Intake") valve flap breaks (1), sometimes with parts sucked into the intake manifold (1) (2) (3) (4) (5) (6) (7) (8) & a well documented example of how a broken DISA flap can ruin your engine (1) & yet another seemingly complex set of misfire codes reputedly traced to a broken DISA valve (1)

Or for the misfire thread question:
- How to diagnose a BMW E39 engine misfire (1)

And, for vacuum leaks:
- How to locate all problematic (between 1/8" & 9/32" ID) 3.5x1.8mm, 3.3x1.8mm & (between 17/64" & 9/32" ID) 7mm ID vacuum tubing (single material), vacuum hoses (multiple material), 3.3mm OD curved vacuum pipes (rigid tubes), 3.5mm & 7mm ID vacuum endcaps (closed end) & 7x3mm manifold o-rings (1) & 7.52X3.52mm and 9.2X2.8mm fuel injection o-rings (1) & gaskets (1) on the M54 engine & where in the USA to get new vacuum tubing & vacuum caps (1) & what SAE sizes to get for all the metric M54 engine vacuum tubes, hoses, pipes, and caps (1) & correcting the F-connector errors in the realoem diagrams (1) & finding the ends of hard-to-locate vacuum tubes (1) & sorely needed clarification on how the M54 CCV vacuum port works on the M52 CCV valve connection to the fuel pressure regulator connection (1) & how to make, borrow, or buy lean-condition misfire test tools to test for vacuum leaks & lean conditions (1) (2)

etc.

Good luck.

Once again, thanks Blue. That is an invaluable resource and I can tell you put in a ton of work. I'll dive in head first and report back once I locate the issue.

Duct tape the crack in the intake boot

Other things to checK for misfire:
  • Smoke test (Intake boot leak, Vacuum line leak, Intake Manifold Gasket)
  • CCV
  • MAF
  • O2 sensor
  • Spark Plug
  • Spark Plug Boot
  • Coil (swap coil to test)
  • Camshaft position sensor
  • Crank position sensor
  • Fuel Pump
  • Idle Control Valve (ICV)
  • Oil in spark plug sockets from leaking VCG

Cleaned the idle control valve.
Cleaned the MAF.
Replacing intake boot (on its way from bavauto)
Checked the fuel pump filter. Is there any way to check the pump itself?

Going to continue moving down the list. Thanks!

Here's my picture of the autozone fuel pump testing kit, for example, which is available free of charge for a 90-day loan (1):

There should be a DIY for everything on that list.

Did you duct tape up the intake boot ??
That's the most obvious answer.

Intake boot isn't it. I'm thinking that the lean codes are indicating fuel pump issues. I'll get the kit from autozone and see where that takes me.

Fuel pumps soft fail and can cause lean codes. But also check the CCv lower oil drain hose as well, very common problem.

www.bmaparts.com has good pricing on fuel pumps with free shipping if you fine the online discount code, I think it may be specE30?

This thread covers a lot of the common 6 cylinder BMW driveability issues.
