c20let engine, the codes are coming up as -
13 - oxygen sensor, no voltage change
16 - knock sensor cicuit, knock signal
lambda and knock sensor. my lambda was being used in a mates cally turbo and worked fine. was sitting about 2 months before going back into mine though.
also, is it likely that the knock sensor is faulty? ive never heard of that happening. the car ticks over at about 1200 and tries to drop the revs, but it doesnt.
any ideas what to do? or why these codes are coming up?
