must be the morning for code 43

[rrhayden]

I was idling down the street this morning shortly after starting the car. The check engine light came on for about 30 seconds and went out. I just checked codes and it had a code 43 knock sensor. Since the light went right out, should I be concirned at this point?

Thanks

Put your car in 6th gear at about 45-50 mph and lean on the throttle...does it stumble ??? (hopefully you have a manual trans.)

 

[rrhayden]

No, it is an auto

have any rough idle problems ?

 

[rrhayden]

Yes, it does idle rough. It feels like it is missing on a cylinder or two.

I'll be interested in any responses to this one!!!!

still working on mine...might have it fixed tonight...if the new knock sensor works.

can anyone tell me what a "knock sensor" is?

I'd like to know what a "knock sensor" is. Thanks

There are two of them on a LT1 they are screwed into the block. They detect engine detonation ( pinning ) and tell the computer to retard the spark advance.

how about on an L98?

Are they in the same place on an L98?
