it’s a 525i m50 motor in 1988 e30
This wasn’t a problem to I had a no start issue from accidentally cuttings. Wire. After installing a engine wire harness cover
has a misfire rn coming from 1 or more cylinders
something electrical related
coils
dme or wires
or plugs I will figure it out
what grounds are tied to ego heater
never had this issue before trying to get cel off
I HAVE A CEL CODE 1264
I bWENT AHEAD AND REPLACED THE O2 sensor
still no change THE CODE READS OUT TO BE EGO HEATER CIRCUIT IM THINKING I
has anyone had this code with a 24v swap car ??
1264 ego heater
o2 sensor heater relay.
anynadvice where I should start with the multimeter ? Where to check for power first ? Or where I should start searching for a short
Also using a non oem o2.
also I swapped out dme’s when diagnosing the a start issue in the past. Soo I’m not sure which one I originally used and if that could be the cause. Going to start tracing all wires back and lebelung them to rule out cut wire or short
I had a no start issue form accidentally cutting a wire that went to ignition switch.
It’s possible there’s another cut wire I missed.
where is this relay related to this
Any direction on where to start would be helpful
willing to pay for good advice
