bearbalu Posted December 31, 2004 Share Posted December 31, 2004 I am getting cylinder 2 misfire. Subaru service manual seems to indicate that 1/3 and 2/4 have same resistance. Looking at spark plug wires 1/3 seem like same wire (label says 1-3) but 2 and 4 seem different (labeled 2 and 4 respectively). Can I swap them just for test? If not, is there a simple test short of buying new wires. Link to comment Share on other sites More sharing options...

bearbalu Posted January 2, 2005 Author Share Posted January 2, 2005 Thanks folks. I tried it - seems like perfectly acceptable method. Cylinder 2 misfire didn't move to cylinder 4, so I know it it'sn't the wires. Cylinder 2 misfire however seems to have vanished mysteriously.

bearbalu Posted January 3, 2005 Author Share Posted January 3, 2005 One thing I have learn from reading on this forum is that blind "replace and pray" usually leads to expensive repairs, specially CEL. Same applies for overheating - I suspect I ended up doing head gasket job because I diagnosed the problem to thermostat, it was probably a clogged radiator. Repeated overheating lead to blown head gasket. Here are a few things to try when one gets a CEL with cylinder misfire: 1. Swap spark plugs/spark plug wires/injector to see if the problem moves to another cylinder - if it does, you know what exactly to replace! 2. Measure the resistance of ignition coil/spark plug wires, injector connector against specs, before assuming they are bad 3. Listen to click-click of injectors to see if they are working okay.
