RE: 164L '91 - Oxygen sensor replacement - advice please

["David Hanley" <David.Hanley1@domain.elided>]

But the cat is underneath the gear stick, and well clear of the engine.
I can foresee a problem finding the cable connector on the V6, but would
have thought exhaust would hang in the same place (same exhaust on TS as
V6).

I'd check my V6 166, but it's a bit dark and wet outside tonight.

Regards David.

AHA!

I think I understand--You have a twin spark, which is a much smaller
engine than the V-6 in David's car--perhaps the larger engine makes the
exhaust system much more crowded, thereby require the dismantling.

Any thoughts, anyone?
