Knock sensor give bad idle?

[freshlane]

Today I got two cels one was for IAC and the other for the knock sensor. I cleaned the maf and the IAC CEL went away but the car idles like crap. The knock sensor is bad (oozing out the bad). I wanted to know if this could cause poor idle conditions?

Common people. It is just a simple question. I've searched but need a yes or no basically. I am changing the sensor I just want to know because I don't like having answers when is comes to my dsm

i know it will start with a bad knock sensor. but i don't think the knock sensor would be all that active at idle. make sure you got all the vacuum lines hooked up that might be the problem.

A bad knock sensor should not have any effect at idle - the ECU ignores the knock sensor at low RPM's. A defective IAC can certainly cause a rough idle - the IAC is located at the throttle body. I was wondering why you cleaned the maf in response to the faulty IAC CEL?

Did your engine run poorly before you cleaned the MAF? . . .
