i bought a 2000 s10 ls with a 2.2 from a friend . they were driving it down the road and it just died and they never figured out the problem. the day i went to get it i decided to check the fuses under the hood and the ecm 1 fuse was blown so i replaced it and drove it home. today i took it on about a 60 mile drive and when i got 1 mile from home it blew the ecm1 fuse again so i replaced it 4 times to get it home . i ran the codes on it and the only one is p0138 bank 1 sensor 2 voltage high can a bad o2 sensor short the ecm and blow the fuse ?
