1995 wrx misfire on 1 cylinder
 
Hi guys i have a 1995 wrx. Which has all of a sudden decided to develop a misfire on 1 cylinder.

It seems like it is not getting enough voltage to the coil. It has a 12 v live all the coils do but the other pin in the plug that plugs into the coil (which i assune is a negative?) shows 2v on that particular coil but 10v on other coils.

Does anybody have a wiring diagram of the idnition coil and how the ignition system is workkng on the 1995 wrx i understand they have a ignitor also. 5 pin entry plug and 4 pin exit pin which i assume is the wiring which goes straight to the coils?

Has anybody experienced this before and any help would be appreciated thanks guys.

Have you checked for cracks under the rubber boot on the coil pack ?

No I havent mate will do tomorow. I dont think its the coil but will try a coil off a diffrent cylinder to seenif the misfire is still on the same cylinder. Are they know for the ignitor to pack up?

euro stock them, but they are 140 quid,
as mentioned on the other thread, the conversion is a big improvement, and isnt complicated.
