When my95 uk wagon comes to a junction or i put my foot on the clutch the reves sometimes drop right off and the car stalls. Sometimes it nearly stalls and then corects its self.I've got full decat, hks filter, larger intercooler (top mount off a uk300)and dawes set at 15psi.

 

Sound like a faulty MAF sensor. A select monitor from Subaru should tell if it's faulty.

Cheers,

George.

 

My MY00 was the same.... ran fine except tickover would alternate every couple of seconds or so between next-to-nothing and 1300 rpm.........

New air flow meter sorted it - under warranty, so I dont know how much it cost.
