Hello
Thought you lot may be able to help me with all your knowledge.
Have a bit of a problem on my93 wrx. Seems to be having occasional misfire. Now this has only happened since i left the car outside for a week in the rain. Is it just a case of taking it on a long run to dry it out?.
Last xmas I did have the camshaft sensor changed on it as it had a major misfire then. Although that was consistent not just now and then.

When the turbo is on its fine and doesnt misfire.

Any ideas?. Thanks

 

My sport had a misfire at anything up to 2000rpm. Drove like a dog, stalled at every junction and would sometimes cut out whilst being driven. Turned out to be the immobilser, only found out when I had it removed on the off chance.
