Hi all basically I have a nova turbo (c20let) and my problem is i keep getting knock sensor fault witch is putting car into limp mode ive tried everything I can think off to try and sort this if I reset ecu it goes off drive but as soon as you put foot down ecu light comes on and goes back into limp mode ive changed a few things that I think could cause the problem witch are
.new knock sensor
.different engine loom
.different ecu
Also ive checked the loom plugs that they are the right way round cu I know the knock sensor and idle control valve are the same plug and its defo plugged into right one
So none of that has worked so could do with help thanks
