My car has recently started blowing the eng sensore fuse. It actually made the car drop almost .5 seconds and the strip the other night.

I looked back and it seems the most common thing is the 02's grounded out...

Could them being bad cause this also, I just extended the wires manuely.

Any other things that could cause this?

 

"I just extended the wires manuely."

Recheck your splices...

 

This might help...

start checking wires...make sure none are pinched around the maf connection or anywhere you can think that you have possibly moved before

or unplug un-nessicary sensors one at a time to find which leg its in. get a wiring diagram and good luck. if it blows the fuze every time its easy, replace the fuze with a load i,e light bulb then do the wiggle test, wiggle the harness when the bulb goes out it has lost its ground which is your short, if the wiggle test fails unplug everything on the circut one at a time i have seen shorted sensors before. to bad most shorts are intermittent and happen at the worst time. i once had a 350Z of a customer of mine which would blow a fuze on hard left turns on the 3rd lap around the track. tiny pinhole in a wire took 3 weekends at the track to find. goodluck!
