BM3 LOG/// weirdest symptoms of a tuned F10 after injectors replacement
Hi guys , so my F10 is a mess rn and idk what to do.
So let’s start with what the car has been done to it : Stage 2 E30 agg on bootmod 3 Intercooler upgraded Catless downpipe, straight piped Pretty much a full bolt on except hpfp upgraded just yet waiting on dorch to ship the pump. I fill it with 6 gallons of gas btw for almost a year now Anyways , the car has been misfiring for some time last year before e85 gas was being put in , I’ve asked this forum n yall said if it can’t b the plugs or the coils , it got to b the injectors , at that time I only replaced the plugs and got precision raceworks ignition kit , Keep in mind oem injectors were never replaced and the car has 69,443 miles Fast forward to last week my car got the EU6 injectors , so I was like fuck it since imma get the stage 2 dorch hpfp lemme get the EU5 injectors , and that’s what I did , I replaced 3 things while I was gon open the car for the injectors : Ngk plug: gapped to .20 ✅ I contacted PR n asked what do I gotta change the wires for the coils or the whole block thing , they said the wires , so I’ve ordered 6 wires and replaced those ✅ And replaced the injectors with Eu5 and coded it with protools app on android . First startup the car was idling rpm crazy , but it Settled down after it warmed up , Then I got a CEL and saw this first codes : 118001 Mixture control: Mixture too lean 140302 Combustion misfires, cylinder 3: harmful to exhaust gases after starting 140502 Combustion misfires, cylinder 5: harmful to exhaust gases after starting 140002 Combustion misfires, several cylinders: harmful to exhaust gases after starting 140310 Misfires, cylinder 3: detected 140510 Misfires, cylinder 5: detected 140010 Misfires, multiple cylinders: detected 11CF30 Mixture control: Group error At that time , it was November 7th , but it would only show symptoms of misfires upon startup not during WoT Fast forward to November 9th at 5:18pm I got these codes upon wot 118001 Mixture control: Mixture too lean 140102 Combustion misfires, cylinder 1: harmful to exhaust gases after starting 140110 Misfires, cylinder 1: detected 140302 Combustion misfires, cylinder 3: harmful to exhaust gases after starting 140502 Combustion misfires, cylinder 5: harmful to exhaust gases after starting 140002 Combustion misfires, several cylinders: harmful to exhaust gases after starting 140310 Misfires, cylinder 3: detected 140510 Misfires, cylinder 5: detected 140010 Misfires, multiple cylinders: detected 1BC112 Zero gear sensor, electrical. Snort I cleared the errors and fired my car up at 8:49pm and got these codes 140302 Combustion misfires, cylinder 3: harmful to exhaust gases after starting 140502 Combustion misfires, cylinder 5: harmful to exhaust gases after starting 140002 Combustion misfires, several cylinders: harmful to exhaust gases after starting 140310 Misfires, cylinder 3: detected 140510 Misfires, cylinder 5: detected 140010 Misfires, multiple cylinders: detected 118001 Mixture control: Mixture too lean Fast forward to November 11 I got these codes , the reason why I clear the codes is bc I only use this car to go to gym after work so for the whole month I’d only typically drive the car 50 miles anyways : 140401 Combustion misfires, cylinder 4: Injection is switched off 140001 Misfires, multiple cylinders: Injection is switched off 140410 Misfires, cylinder 4: detected 140302 Combustion misfires, cylinder 3: harmful to exhaust gases after starting 140502 Combustion misfires, cylinder 5: harmful to exhaust gases after starting 140002 Combustion misfires, several cylinders: harmful to exhaust gases after starting 140310 Misfires, cylinder 3: detected 140510 Misfires, cylinder 5: detected 140010 Misfires, multiple cylinders: detected 140011 Combustion misfires: Injecton s And I’m like .??????? I thought cylinder 3,5 was bad but now 1,4 too? I cleared the error n they gone but 3,5 was kept showing Here’s this : central gateway codes if it ever matters : 101008 Non-resolvable ambiguous routing - SG not in the SVT target table 100600 Flexray protocol startup time is too high 100104 HW Weckgrund ZGW 100001 VemResultSvtCheck - identity check: Differences between the SVT actual and SVT target have been recognized. anyways , Today , I finally go to gym again, rough idle , drives smooth but I feel like there’s loss of boost pressure and power and mpg is 9.0 While driving out of no where I got a “Drivetrain malfunction error” 5 seconds later it disappeared, I parked my car checked BimmerLink, bootmod3, and xHP for diagnostics. Nothing for the drivetrain But upon checking bootmod I got these codes : 119304 Rail pressure sensor, plausibility: pressure too high before engine start 118001 Mixture control: Mixture too lean 140302 Combustion misfires, cylinder 3: harmful to exhaust gases after starting 140502 Combustion misfires, cylinder 5: harmful to exhaust gases after starting 140002 Combustion misfires, several cylinders: harmful to exhaust gases after starting 140310 Misfires, cylinder 3: detected 140510 Misfires, cylinder 5: detected 140010 Misfires, multiple cylinders: detected I don’t know what to do anymore , I thought replacing all 3 plugs , injectors and coils would do it but it made the car even worse . On top of that now , I hear a sudden “thumb/clunk,” wtv I let go of the gas pedal from the middle of center console or in the rear seats , I hear that stomp sound when I press on gas pedal or let go , it lowkey sounds like it’s coming from the tank under the seats . Idk what to do anymore please help oh yeah here’s the log I’ve logged April1st (the only log I have before I swapped the injectors) November9th (the day I turned the car on after I swapped all 3) And today after mid 70% wot |

Like I already contacted ecs tuning , bc before I’d install the injectors , 3 of them were opened packaged with signs of used / dirt marks , since now it’s been misfiring does the plugs needs to b replaced too? What about the pr coils wires?
