Hello

 

Well on my way home my car cut out and then did the missfire thing again.

It has been sat for the week as i have been away i warmed it up for ten mins before i drove home ( slow drive ) it was also raining any ideas ?

 

I think somone said on here about the air filter getting damp or something like that it has an apexi air filter on it if that helps or could it be a problem with my maf.

 

It only seems to do it when it is raining or after rain any ideas?

is it a missifre or is it more like the car is hesitating? as you said it could be water coming into contact with the hot wire in the AFM (do you have your splash panel under the pod?) Pull out your pod and dry it (you could leave it in the sun- assuming you get sun over there lol :p) and pull out your AFM and give it a spray with carby cleaner and let it dry. Would also be a good time to clean up the AFM plug if there's any corrosion on it. Hope that solve's your problems.
