plug leads
I have just run through my ign leads and coils for the 86 engine and have found
Coils
prim .5 ohms
secondary, 5.56 k ohms
prim .5 ohms
secondary 5.65 K ohms
Coil leads
1.1 k ohms
1.03
leads
#1 4.00 K ohms
#2 4.02
#3 4.06
#4 4.26
#5 4.17
#6 3.97
#7 3.79
#8 3.97
all the leads show to be about 1 k ohms higher than what the factory manual states they should be, I didnt find anything about the coil leads though, and the coils appear to be in spec.
does anyone know if this is too high to cause a poor runing/unable to rev situation.

The leads themselves shouldnt have any significant resistance, it should all be in the plug connector. On my 83 16V, the plug connectors screw off the end of the lead. The connectors are marked 3k on mine, and they read very close to it. Separately check the connectors for resistance, and for markings moulded in them. Then check the lead by itself for resistance, and flex the lead around while you have the meter on it to check for internal breaks that wont show up all the time - I replaced my whole set a few years ago, and later found only 3 of them had real problems.
