My 94 WRX has a recurring Knock Sensor fault code causing a 'Check Engine Light' to some on and the performance to be reduced dramatically.
My understanding of the situation is that the knock sensor is sensing 'knock' (miss-firing) and adjusting the timing to suit, when it get to its limit it gives the fault.
I have changed the knock sensor for another second hand one and it gives the same results.
I noticed that the exhaust is blowing at the flexible joint just below the turbo - could this cause mis-firing??
Alternatively, has anybody had this problem and found faults with either the ignition system or the injectors??
This is an exasperating problem, I hope that someone out there has the answer!
