The E46 M3 Journal
-
Showed the M3 some love today. Full wash, vacuum, wiped down the interior and did the windows. 3 hours of cleaning! I used to detail so I like to think I'm pretty efficient.
Also replaced my fuel pump relay located in the trunk, passenger side. 61357892976 part number black relay.
It's like a scab... you gotta pick at it.
I noticed a difference in power delivery immediately. Smoother and a lot quicker. I got pretty excited so I went over to O'Reilly's to scan and clear the computer. Too rich bank 1 & 2. After clearing it I took a mild drive up to Bayside then took Lake Dr. back home. No light and I averaged 21ish MPG!!!!! I was getting 13 before.
Will the M3 be back at its full potential? Will the infamous engine light stay dark? Stay tuned in to the next adventure of the 2003 money pit! Sponsered by the Cabelas Club VISA. Rack up your card, mount racks on the wall!
Still need to microfiber the interior to get the streaks and dust cleared off everything.

Engine light is on...Need to man up and do the O2s ASAP.
It still is running better with the relay though. Or because I cleaned it?

Have you tried smacking the dash?
Usually takes care of my lights (when the car wasn't in a bajillion pieces)

This is riveting!

Pre Cat O2 sensors have been replaced with OEM parts and triple checked for the correct position.
Now I'm getting these codes:
DME,DME Number: 7842975 Current: 2159.4h Last Cleared: 2158.3h
140,1,38,2480,Knock Control Deactivated/Knock Protection
175,1,80,5120,Fuel System Diagnosis Bank 2
149,1,38,2040,Fuel LevelI have just cleaned my filter and re-oiled it. I'm going to drive it all day today to get any extra oil out of the filter then I'll install the new OEM Mass Air Flow Sensor.
Do I need new knock sensors??!!
@DrLeadFoot
-
Never!!
I forgot to mention that the filter was uber dirty!

Light is back on. I guess I need the fancy BMW scanner to recalibrate the ECU with the new MAF sensor.
Also I'm going to spray brake cleaner around the intake manifold and throttle bodies while the car is running to see if there are any vacuum leaks.
If all this still results in a engine light Frank Smith will send me an ecu to pop in to see if my ecu is bad. From his experience the coil drivers in the higher milage cars get lazy.
@DrLeadFoot

Same story, I'm having them send over the stock tune just to be 100% that that's not the issue.
I have a feeling a new ecu is in the works.
@DrLeadFoot
-
Frank Smith should be sending over a stock tune today.
The M3 has been having starting issues for awhile now. It cranks on the first try then no start. Second key turn it cranks starts but creeps up to idle very slowly. Ideas??
@DrLeadFoot
-
Maybe. I was all over Milwaukee yesterday I can't remember my time frames.
Stock tune to come today.
I also had a nightmare that the M3's head gasket blew. I have to get these cars fixed!! Haha
@DrLeadFoot
-
The stock tune made a huge difference being that the car doesn't sound like a old ford pickup with a bad exhaust manifold gasket. The light still came on. After talking with Frank Smith from tuning tech we think the 2 cam and crank sensors should be replaced. I will order those tomorrow. I'm thinking that is why the car doesn't start on the first try. I also have replaced almost everything else that would throw the o2 sensor codes.

Break My Wallet So the car runs better on the stock tune then?
I'm thinking the file that was on the computer that he made the tune off of was of the car running poorly.
I'm getting the 2 cam sensors and crank sensor tomorrow to see if that fixes the problem.
@DrLeadFoot
-
Next to do after I replace the sensors. The music gets you in the wrenching mood.
@DrLeadFoot
-
Ordered cam and crank sensors. Should be in tomorrow afternoon.
