when i got the car, it had this code already i thought it was just a simple bad plug. changed them all and ran the same. i checked the timing and its on point but i may just do a whole TB WP tensioner job this summer sincei dont know when the P.O. did it on this car.

my TB is installed correctly. i had to remove it to change my injectors and to do my starter so i know its in there good.

The other thing alldata say is to check the tone wheel mounting for the cam and crank, check the teeth and then the wiring.

This is what I see on alldata, from what I read of this, it is a general code that could be caused by serveral problems, but basically the sensors, wheels need to be closely checked. Or at least that's the way I read it.

nthach, do u have a picture showing this little trick?
I don't but the damper is near the EGR valve, and there's a fuel hose connected to it.

I'm thinking of doing a fuel pump replacement write-up though.
