i had to go buy this sensor(55 bucks)becouse i cant find the old one now i dont know how it mounts there are no mounting holes on this thing the wire plug is behind the motor
Right, thats the EGR Transducer and goes here:
As you can see, you'll most likely need to remove the cowl to get at it. Where is the silicone hose that plugs into the bottom of it and going to the EGR metal pipe? Without it you will get a lot of detonation which will eat your head gaskets, need I say more. Good luck
