Knock sensor
Hey again. im throwing a code 28 in my 92 svx lsl. this is for the knock sensor on the left side. the check engine light will only come on every once in a while but never stays on for long. i was wondering if this was the sensor failing or if i have a bigger problem on my hands here. how often do these things actually fail? i found one for 42 bucks at auto zone. just wondering if you guys think i should replace it or if i should be looking for a cause for this code being thrown. also when i go to stop at a light or something for more than about 5 seconds the cars idle will bounce up and down quit a bit like down to 300 and up to about 800ish RPM would this be related to the knock sensor? im not trowing any other codes just the 28. thanks Paul
