Resistance Ignition / plug Wires question.
history- poor running 99 ML320 for the last 600 miles. Since the rough running ( rough idle sometimes wont accelerate) the following parts replaced,
The cats
Spark plugs ( seemed to help a bit)
Mass Air Flow sensor.
I know next to nothing about resistance. I just checked one bank and they were all between 2200 and 2300...except one at 2800.
I read a generic forum that read 4000 is normal.
PS 20,000 miles ago replaced the furl pump and filter. last codes were PO170 PO173.
Thanks Steve
