Problem: 4.0 '89 engine runs bad...
Hi to All,
I've a problem with my 4.0 '89 after changing the O2 sensor,
in particular the engine starts, but it hasn't power and has some difficults
to increase RPM, and some small detonations are present inside airbox
during this difficult phase.
What can be the problem?
The new O2 sensor (NTK)?
THanks!
Lucio.
