Hello, Im afraid I have a intermittent knock sensor problem.about 6 weeks ago the car was driving like a pig, anything more that 2krevs it would missfire fault code 34 (knock sensor) flagged up.
I changed the spark plugs, cleaned the distributor and sprayed out the distribution lead ends, this fixed the misfire I erased the fault code and this has never come back since.
About a month ago on my way to work the check light was just flickering on/off (apparently this indicates a knock) checked the fault codes- No faults (55) conveniently on the same day I was fitting a new oil cooler so whilst I had it on the ramps I cleaned up the sensor and connector for the knock sensor, fault light hasn't been on since then... untill today.
on my way to work again today again the light flickers on/off still no fault codeIm pretty sure there's no knock because the car's driving really well and the 34 fault code hasn't rerturned. normally I would say just clean up the sensor and the connector again but surely if they were at fault then I would get a fault code.does any one have any experience with knock sensors- is it normal for the light to flicker if there is a knock, a sensor fail or a wire fault Im just baffeled there's no fault code to back up the lamp being on.
