The E46 M3 Journal

I cant believe all the crap you can read off newer control modules. That would drive the OCD crazy with all the faults that come up
You have no idea, I bought the scanner that can tap into every module in my e46. It is ridiculous what it will record, "low voltage passenger side mirror" for example. It was a shadow code so it wasn't actively happening. If you unplug anything it will remember.
Gets crazy, and that's on a 2000, imagine what the 2014 cars are like.

I printed the codes from an autologic(?) Scanner. It comes on right after start up after clearing. I have frank smith software.

Ok so its a present fault. Do all the misfire faults come back? cylinder 1 and 2 could be the culprit and causing the rest to store faults also. What if you remove the software and clear? Easiest thing would be to swap coils and plugs with differenct cylinders just to make sure its not either of them. I know you stated they were new but still. Next would be fuel injectors.

Okay, got a lot fixed.
- The EGT sensor wire had sheared off and replaced with a new one.
- One O2 sensor was replaced.
- The #6 injector was leaking and was replaced.
- Valve job was due so got it done but everything wasn't too out of wack.
- Hood latch sensor was replaced.
- An exhaust stud on the #5 cylinder was missing. Got a new one in there.
- A new belt, tensioner and idlers were all replaced.
- Rear trunk latch was replaced.
The cherry on top was the previous shop that installed the headers, after extremely scratching off the ceramic coating, more than likely removed the passenger side engine mount to provide room. Well, while Urban MotorworX was re-installing the missing exhaust stud he noticed the engine mount didn't have any bolts. After further inspection only one bolt was still on holding the broken piece of the engine mount to the block. THE WHOLE ENGINE WAS RESTING ON THE STEERING RACK! That would explain the weird vibrations I've been dealing with. This is also why the EGT sensor was sheared off. Matt installed two bolts to bandaid the problem for the time being. Tuesday the new arm will be here. Not sure if the previous shop over torqued the bolts and with my hard driving they came loose or if they were tight in the first place *cough, exhaust stud, cough*. After thousands and thousands of dollars spent on fixing issues of incompetent mechanics at this shop my word of advise to the community is please steer clear.
The car is running amazing at the moment. I am getting a too lean code from bank one and two but I think that might be the tuning that needs to be tweaked.

Random pic on Lake Dr.
Took the car into Urban Motorworx for the engine mounts and passenger side arm as well as a look into the too rich bank 1 & 2 codes.

Might need to do a head gasket on this beast. Compression test to come.
Doesn't seem too tough. I did a eta to i head swap 11 years ago so it has to be like riding a bike.
