The only thing I've done is had HPE put some Hooker LTs and ORY in 2 weeks ago, along with tuning it. The reason I say this is because searching has shown that sometimes the O2 wires get burned or pinched against the heat shield. I just looked and noticed my driver's side 02's end is right up against the shield. Is there anything else that could cause this?

 

I'm not really sure about the engine sensor fuse,but I do know that when my o2 wire got freyed and grounded out I threw a random misfire code. Actually it happened 2 times, once on each bank. It was the main wire that gives you the readings for an A/F gauge that got messed up. weird thing was it never threw any kind of 02 code. Car bogged and sputtered under acceleration and ran really rough. I did everything that you would normaly treat a misfire for, plugs,wires,coilpacks and injectors, fuel filter everything, until I finally tracked it down to the 02 sensor. Funny thing was it showed a misfire for a specific cylinder each time. Of course the second time it happened I new right where to go. you might try posting in the pcm section, jimmyblue, horist and a few other guys have helped me out with ?'s. Smart individuals I must say.

 

and for some reason that code is in there twice

 

which code is in there twice. If you are talking about your code that is a Fuel & Air Metering, Aux. Emission Controls code. PO102 is Mass/Volume Air flow circut Lo input. If you were talking about me it was on 2 different occasions

 

P0102 is in there twice, and if I replace the fuse it just blows again.

 

when i had the problem w/ the eng sen fuse blowing i found it to be the wires going into the weather pack conector that conect to the MAF sensor were damaged. from them being bent back over time the wires inside were broken. only other thing i can tell you is to get a repair manual w/ wire diagrams and trace wires if it keeps up to see if you can locate a short.

Fuse blows immediately. That's dead short to ground. Look for pinched wire, bad insulation, load wire touching return wire bypassing the load, etc. This is basic stuff that applies to all blown fuse situations. Check your work. Someone got careless and tightened a HOT wire against bare metal. That's when your fuse does the job it was intended to do.

 

Well, I have looked over it and can't find anything.

To the shop it goes.
