engine sensor fuse
HELP fellow LT1'ers!!! Earlier I was driving and my SES light came on, and my reverse (M6) is locked out. Sometimes the car idles funny, and @ 5000 rpm it stutters. Has brand new o2 sensors. . . .. Found out that its popping a fuse under the hood inside the relay box. the fuse says "ENGINE SENSOR" fuse. WTF is engine sensor fuse?????? what runs off of it???? Anyhelp would be appreciated.... THANKS

just to let you know i did about 4-5 grounds that are in between the front bumper and front wheels
.....there were more but they where on the engine so i had to make sure that they where grounding properly too 
look on the core support and right behind the battery. there are grounds there. go ahead and just find them and start cleaning. i wouldnt pass over all them just to find the pcm and knock sensor grounds. id just make sure i found those as well. also make sure the eninge ground is good. it should be on the drivers side cylinder head. i think the front or back. im getting my cars confused a little right now so you should be looking for a bare braided metal strap

Yeah, the ground for the knock sensor is the engine block. The sensor screws into the block, and it is grounded through the body of the sensor. That would not be your problem.
It sounds like you have a short somewhere, that is the only reason why you would be blowing fuses. If it was just a bad ground, you wouldn't be blowing the fuse.

You can often pick them up off of Ebay.

update: cant find the damn short anywhere. Ive checked all the grounds and they are well connected, bolted, etc. I have tried using my friends MAF, and the same happens. Anyother suggestions ????
