Hi guys ,

 

 

Looking for some direction here i have a impreza sport special 2000 , now recently got it mot serviced ect . Now  about a week later my CHECK ENGINE LIGHT comes on but only seems to happen when climbing a hill , now i am totally baffeld by this , i also took it to get diagnosed to see if i can get a code but nothing showed up :-( when the car check engine light comes on its really unresponsive when it goes off its fine , thanks in advance if anyone can shed some light on this .;-)

I would say crank sensor is failing under load. That's my guess anyway :D  

Thanks m8 will check it out see what happens ;-)

+1 or maybe the dreaded Maf ??
