2 cylinders misfire

OK let me start off with I'm new to VR4's but i do have plenty of mechanical knowledge. That said, my vr4 is misfiring cylinders 2 and 4. So i checked the coils and they are good, wires are good, plugs good. So basically it seems as if I'm not getting anything from the coil closest to the firewall. My only guess is that either the cam angle sensor is bad or the crank position sensor, now does that sound right? Any ideas would help, thanks.

I believe that if a coil went out, 4/1 or 2/3 would be missing together.

 

The cam angle sensor is used as both a cam and crank angle sensor on a 4G63. Like Marvin said one coil is 1-4, the other is 2-3. Before anything, have you changed the Capacitors on the ECU yet?

 

Ok my mistake its not 2/4, its 2/3. I had 2 extra coils and i've tried both of them and still misfire on 2/3. I did not know that the capacitors needed to be changed, i will probably replace those within a week. Is it possible it is the capacitors?

Check the power transistor

 

Problem solved replaced ignition control module and problem solved thanks guys!
