Robby1870 Posted October 13, 2003 Report Share Posted October 13, 2003 Possibly the knock senosr?!?!? Thats the best guess I got. Quote Link to comment Share on other sites More sharing options...
Jeorge Posted October 13, 2003 Report Share Posted October 13, 2003 Is it a 2.8/3.1L? when Reaching from the top down is it up and to the left a bit? like say 3 inches away?? if so thats where your winter heater is...if not then I dont know what you are talking about.... Just Changed the Crank sensor on a buddys 3.1L and that is what was there on his.... Quote Link to comment Share on other sites More sharing options...

Robby1870 Posted October 14, 2003 Report Share Posted October 14, 2003 please do tell us more about this knock sensor thingy. Monty Its sense pre-detonation, and retards (I guess) spark timing so that pre-detonation or knock doesnt occur. Unless something is wrong with a n/a 3.1L, there will usually be no knock at all (low compression). On a turbo with high boost, you will see knock.

Monty Yeah, you should mainly worry about knock on any boosted car or really high Compression Ratio Quote Link to comment Share on other sites More sharing options...
