2002 330i loss of power 9 codes!!

Sorry to bug you guys but I stumped on loss of power on my 2002 330i 230000 miles.
It was 35 degrees here yesterday and I started car, ran fine and idled fine drove prolly 75 miles. Before yesterday I did have a loss of power here and there but once I shut of car and restart it be fine. But yesterday it kept doing it, I started to go up long hill! I figured it would stop and I had to make it home so I babied it up hill once at top smelled like wires melting but when I pulled over and look at engine the back of the engine by firewall had steam comin from it so I looked under car and it looked like the resonator shield was so dam hot it had steam coming off the shield!! It wasn't rainin but I do have a small oil leak that may dripped on shield but it was the whole shield with steam coming off like if the resonator was glowing red but I couldn't see only shield! So I drove into advance and ran codes! It produced 9 codes here they are..

Do you guys think it might be the cats clogged? That would be reason for the resonator being so hot or pipes between resonator and two cats? If I had a faulty cat would it throw these codes? Thx

I did not look all of your codes up, it is best for you to research the code definition and post this along with the actual codes.

I can tell you at a minimum there is a Lean problem with misfires. Cutting the engine off and restarting it clears the Misfire With Fuel Cut Off the DME enables to protect the catalytic converters from too much raw fuel. BMW does this on purpose.

Lean problems are typically due to intake and/or crankcase air leaks which these engines have MANY of after about 8-10 years. This is NORMAL on these cars.

Intake boots, CCV valve and hoses, leaking power brake boosters and weak fuel pumps are the primary problems with these cars after 8+ years.

You clearly have some other problems, however, I would resolve the Lean problem first.

Read info in my signature. Get the OBDFusion App and interface for your phone, read my comments in this thread - http://forum.e46fanatics.com/showthread.php?p=16727145

Smoke test the intake and crankcase if you cannot find the vacuum leaks -

I took the approach on my 2006 330 E46 convertible at 80k at its 8th birthday, I replaced EVERYTHING.

CCV & Hose, Fuel pump and filter, Intake boots, valve cover and OFHG, belts, idler pulleys and installed a new O-ring on the DISA as the DISA was replaced at 40k under the Bumper to Bumper Warranty and was still in good shape.

This way, I have another 8-10 years of no headaches.

EVERY E46 needs this.

STFT are MAX'ed out.

With STFT maxed out and the LTFT @ 0% it sounds like the engine is not in Closed Loop, but without useful info, there will 20-40 more posts to this thread.

Chances are there may be a massive vacuum leak, these engines are WELL known to have massive vacuum leaks after 8-10 years.

Need data, your tool does not appear to be able to Log. Logging saves A LOT of time, but you need to have a tool like OBDFusion and learn how to Log.

Suggest you read this thread - http://forum.e46fanatics.com/showthread.php?p=16727145

The Launch tools are pretty good, I have 2 of them.

As for Logging, NOTHING beats OBDFusion on a phone/tablet. You are only looking at $30 or less for the App and interface.

OBDFusion is wireless. Even though you have the Launch tool, you will find that OBDFusion is very handy and you can leave the cheap wireless interface in the console, door pocket or glovebox and you WILL always have an OBDII tool in the car with you.

If you have a smart phone or table, get an OBDII App and interface so you can read the codes along with Live/Realtime or Freeze Frame data then you will know exactly what is going on with the engine fuel management system.

OBDFusion for Android is is $3.99.

Android Bluetooth adapter - http://www.amazon.com/dp/B00WPW6BAE/...BWNPO9BZ&psc=1

OBDFusion, for the iProducts it is $9.99.

For iProducts you NEED a Wifi adapter or a very specialized LE Bluetooth adapter.

iProducts WiFi adapter - http://www.amazon.com/dp/B00WPW6BAE/...BWNPO9BZ&psc=1

The adapter links I posted were some of the cheapest and smallest interfaces at the time, you should search and see if there are others that may be slightly cheaper. You can also get similar interfaces on ebay, but BE VERY CAREFUL where the seller is located. You can wait WEEKS for an interface from Asia either via Amazon or ebay. You can a US seller that has inventory in the US. I ALWAYS make sure any Amazon items CLEARLY state "Fulfilled By Amazon" before I pull the trigger.

Or for iOS and Bluetooth see special note below.

This info is new/hot off the press, OBDFusion WILL be supporting Bluetooth on iOS.

BUT, PLEASE NOTE. For iOS to support BT it apparently has to be some Low Energy version of Bluetooth. There are only a few of the Low Energy BT interfaces on the market at the moment, or at least that OBDFusion developers have fully tested.

The LELink Bluetooth LE adapter.

Check on Amazon for LELink info and pricing.

The Carista Bluetooth LE adapter.

http://www.caristaapp.com/hardware/

So for the basic OBFusion, you are at $30 or less for iProducts using a Wifi interface or slightly more if you choose a Bluetooth LE interface and under $20 for Android. Very worth while once you find out what you can do with these Apps.

If you want to step up to a faster and higher quality interface, check out the OBDLink interfaces, there are 3 versions of the interface. Note the OBDLink interfaces come with an OE version of OBDFusion so think about that before you decide to buy OBDFusion, it may save you between $4 and $10 on a duplicate App.

First, DO NOT CLEAR CODES YET. If you clear codes, you will loose Freeze Frame data, capture Freeze Frame data before you do ANYTHING.

Read my comments in this thread, note that OBDFusion used to be called Touch Scan.

http://forum.e46fanatics.com/showthread.php?t=1080334

Read this about screen capture for Android, I assume this is what you are running - http://www.greenbot.com/article/2825...oid-phone.html

Set up DropBox Free.

DropBox Info

Also you need to set up a DropBox Free account and learn how to upload the .CSV files to

The easiest way it to set up a DropBox Free account is on your computer.

BUT, WARNING - YOU DO NOT WANT TO INSTALL THE DROPBOX SOFTWARE. IT WILL DO SOME CRAZY THINGS IF YOU DO NOT DISABLE AND MANAGE IT.

What you do is during the DropBox Free sign up process, once you enter your user name and password, when the prompt shows up to download and install the software, just use the Back browser button. This will take you to your Account and then you can upload the files either directly from the phone once you enter the DropBox user name and password in the OBDFusion App.

In the OBDFusion App under Settings, DropBox - enter your DropBox user name and password. Then you can seamlessly upload things to the DropBox account from OBDFusion.

Then when you find the files in DropBox, choose Share, then a URL will pop up, just copy and paste the URL back into a forum reply here.

In an ideal world I like to see 3 Logs that are 4 minutes in length once you figure all of this out.

4 minute cold start, do not touch the throttle or drive. Make sure you have the App connected before you actually start the engine. Close the App after each 4 minute Log so they are not too long.

4 minute warm idle in park or neutral.

4 minute steady highway cruise in the range of 50-65 MPH. Try to find a flat and open stretch of road, use cruise control when possible.

Have fun.
