Under hood fuse for o2

[SuperDaveGSE]

Is there any reason why it would keep popping? The o2 is not even a year old yet but Im getting codes for the o2 sensor. Every time I put a new fuse in start the car it pops. All this started when I got back from Regal madness WTF.

o2 sensor heating element may be shorted...or its one ofthe others on that circuit

iirc its fuse 21 or something and it also feeds the maf/map and i think the downstream 02 as well.

if its blowing as soon as you go KeyOn then disconnect all loads on the circuit and add them in till in blows...or if you have a pile of fuses, just see if they blow after you unplug a load then go KO

the maf is a fairly common failure but i have seen o2 heaters short before so its best to just check all loads

i did see ken Cochlin near your car so maybe something caught fire

Fuse 29 keeps popping and the Aeroforces says code p0135. the car stumbles on the hyway when I try to get it back up to speed from a slow down. The down stream o2 has been tuned out.
