[V8] Dave's 4.2 5 spd running problem

[Ingo Rautenberg]

That was my next suggestion as well.  Of course, you could have the screwy
problem I had with an almost totally stripped Oxygen sensor sending wire
that caused the car to run super rich.  I ended up replacing the OXS and
re-splicing the wire AND replacing the coolant sensor at the back of the
passenger side head as Keith suggests.
