A couple of quick questions about injectors:
1) For the botched dealer installs, to be clear, were parts 9 and 10 missing on diagram? http://www.realoem.com/bmw/showparts...82&hg=13&fg=15 2) It looks like part 9 is included with a new injector. Is that correct? 3) Can I tell if the injector was installed wrong without pulling it out? It sounds like broken Fuel Rail brackets are one way to tell. 4) Can I physically read the injector codes off of the injectors without pulling them? (I would like to confirm the correct codes with INPA.) Thanks in advance. |

Ok, I have answer #4: I can see the codes on all of the injectors. I can also see the part numbers. The four that were replaced under recall are obvious since they are the newest part number. The fuel rail also does not appear to be damaged and the injectors all appear to be seated evenly.

MY car has been going into limp mode under heavy load for last several months...first it was cylinder 3...i replaced coil, then cylinder 1....replaced coil, now cylinder 4. Any ideas of what could keep causing the coils to go...every time i replace the problem coil the car runs fine for a bit then another one goes....frustrating as hell especially when like most of you ALL i want is my baby running perfect. I just installed a JB3 and bought 10 gallons of 110 octane race fuel to mix in tank. THIS seems to lower the chance of misfire under load for some reason...only had one limp mode recently and the CES light went off after one night...Any help or recommendations would be greatly appreciated.
Thanks

That's a nice torque wrench that COBB usues in the video to install the plugs. Anyone know a place I can get a nice digital one for a good price.
This is the one I believe I saw in the video but in gray (Torque Wrench, Electronic, $469.95) |

your next step is to clean out the carbon build up.

I've got a misfire on cylinder 5 after installing JB4 running Map 1. I was doing a WOT pull when all of a sudden the car started shaking and I got a CEL. I immeadately changed to map 0 with no difference car kept shivering when i touched the gas. When I restarted everything was fine. The question I have is if I put the car in Map 0 now and pull out the JB4 and take it to the dealer will they see only the misfire code or would there be any other codes that indicate a tune? I want them to investigate the misfire, I havent gotten my plugs changed yet under the service plan! (Only 23000 miles (37000kms) on the car)

I started a thread, but not getting much for responses. I have a missfire in one cylinder. Replaced plugs, coil and injector. Same code. If it was carbon, wouldn't it be accross all cylinders not just one? I am lost and need some guidance.

When does the misfire occur? At idle or wide open throttle at what RPM?

How did the plugs look when you removed them? I'm assuming your injectors were coded properly? |

I am not sure it is the fp. If it was multiple cylinders and codes, but I am getting one code for one cylinder. Well I am getting two codes. 10703 and 11170. But I get 11170 all the time and for no clear reason and no one seems to know what it means. I am getting ready to leave the car on the side of the road.

I have not tried that yet. Worth a shot. I may pull the intake manfold and look at what kind of carbon build up I have...but I find it hard to believe it is only one cylinder that would be impacted.
