Plug wire reversal

I'm having trouble with the rear cylinder running properly, so i'm trying to isolate what it may be. Is it safe to reverse the plug wires at the coil to see if the miss moves to the front cylinder??

no, if you have a Multimeter you can test the resistance of the coil, should be around 3.5 I believe.

I'm pretty sure you can reverse them...

Well i found this in the service manual so i'm thinking it is not wise to do Table 1-16. Spark Plug Cable Resistance
CABLE RESISTANCE (OHMS)
Front 1,750-4,836
Rear 4,968-13,427
They tested out good so that isn't the problem! Back to the drawing board.
