>> Ok, what you have is a kind of a "Flooding" feelling at low rpm, no
acceleration,  i'm i right? <<

Exactly.

>> You swap the AFM with still the same problem, ok, let's eliminate this
one (assuming that the connection to this one is good!!! yea, wiring harness
problem, very common!). <<

Remember that the second one is an old one not known to be good either so I
can't discount that 100%.

>> It's NOT the cat... you would NOT reach cruising speed! <<

The cat is 6 months old, I took that out of the equation already.

>> It's located on the thermostat housing, 1.9 and 2.1. I don't remember
your engine. If 2.1L, it's on the far left/front (on the head - left side of
the TH), on 1.9L, it's on the left rear, near the engine temp sender. It's
also blue. <<

I have a 1.9. It's an 83.5.
