Hello everyone! Ok, So my 1999 Mounty 5.0 is misfiring intermittently (every 1-2 seconds) and the O2 sensor for bank 1 is reading a constant .75V - .85V O2 bank 2 is working fine as its fluctuating between .1V - .9V.
The truck was running fine before I messed with it.
All I did was take off the upper intake plenum, and valve covers and painted them to give the engine a nicer look.
I don't really see what i did wrong? Maybe a vacuum leak? I cannot seem to find any using my ears and or spraying flammable liquid. I'm pretty stumped right now and need your guys's expertise.
Only thing I can think of is I have somehow fouled the O2 sensor for that bank. Or... maybe the wires are arcing somewhere to the TMH...
Any advice at all would be fantastic thank you!
