Hi Im in need of some advice , I have recently got my 1st Subaru , that I am using as a project , it is a 1998 Impreza 2.0 sport non turbo , I'm having some problems when running it seems to cut in and out of power and "lags" , the lambda sensor and cat were my first thoughts but then I had further problems , I have changed :
-coilpack
-leads
-spark plugs
-cam sensor
-crank sensor
- checked timing
- checked and cleaned throttle body
the problem still seems to be there and lags in every gear on and off also at high revs the power cuts and returns to idle even when my foot in full down on the throttle then will kick back in after a few seconds , was thinking I should change the MAF , lambda sensor , cat, ? Anyone have any advice as to what the problem could be ??
Thanks in advance
