Is there a resistance that a bad wire will show? All my current plug wires show the same exact resistance except for one, which shows a really high number. It is the coil to distributor wire. The four other wires are showing the same resistance. I have an 86 190e 2.3-16. Any suggestions as to which set of plug wires work the best? The ones I took off were an aftermarket set. I reinstalled a Bosch OE set that I had on the car for about 30000 miles before i changed it to the aftermarket set. I bought this set from Bekkers.
