Gentle pulsing/surging on acceleration
Hi guys, just added a 2001 Forester to the collection car is standard as far as I'm aware (did have an aftermarket filter fitted, not sure on make but defo not K&N looked cheap and was filthy so back on a std motoquip filter).
As far as I can tell the engine is basically the same as the original one from my Bugeye WRX not sure what the standard turbo is though.
The car surges/pulses under anything other than light acceleration, no other symptoms idles and drives faultlessly at a constant speed. Best way to describe it is when you accelerate its like you are pumping the accelerator, it picks up, drops back, picks up etc.
I've tried cleaning the BCS but haven't driven it since, I didn't get any noise in test mode but I believe his is normal, should I have run 12V through it as I cleaned it?
