0/2 sensor change no power
my so called mechanic friend changed my 0/2 sensor on my 2.9 because
the original owner cut the wire at the sensor end and left the connection
end hanging and it meltede on the exhaust before the change it ran a little
rich but revved to the moon now it does not go over 2500 rpms and very little exhaust comes out of the pipe any suggestions? bad or wrong 0/2?
my friend said maybe timing I dont think so what do you pros think?
thanks for the help.
