yes i swapped the coils. one time it worked ok for about 30 and yes i
did try 3 differnt coils. its to the point at standstill my car
shakes, under load theres some vibration in the gas pedal, and from the
muffler the air comming out isnt constant. Does that still sound like
a DME issue?
I'm nopt following you. 1 time out of 3 it changed which cylinder was
misfiring? Or 1 time out of 3 it went away for 30 seconds? The going
away part would not be significant. But if it changed cylinders it
i replaced the same coil 3 diffent times thinking the coil i bought was
defective. Now 1 of the 3 coils i did purchase worked for roughly 30
seconds. Also when i hit the gas pedal i get vibration up to 3000
rpms also the car shakes at idle. will a dme fix this
Possibly, but not likely. Historically the DMEs either work or they
don't. There do not usually only fail on one ignition channel. But I
s'pose it could happen. Best bet would be to temporarliy swap with a
known good one.
It's possible for a power transistor to one cylinder to fail in the DME. If
so, it should be a relatively easy repair IF you can find the specs/part #
for the transistor.
I just had to replace the fan speed controller in the digital climate
control of my 97 328 - apparently power transistor failure. Sudden stop -
that's the way they go.
