My 87 GTI 16v is up for inspection in August. I am 99.9% sure it will fail
for emissions.
What can I do to make it pass?
It has a cat (replaced 30k miles ago), but I am afraid the cat doesn't work
as well as it should as I run the car somewhat rich (and think that its
entirely probably soot-covered at this point - not sure if this is
possible).
I heard of retarding the ignition timing considerably, to help burn all of
the fuel in the chamber. What else? A new set of sparkplugs can't hurt....
What about cam timing? Any thoughts on retarding my cam timing a smidge - I
can't retard it too much as the block has been shaved and I'd rather not
risk pistons meeting valves.
Anyone have any experience with fuel additives to help pass emissions?
Thanks in advance,
Denis G.
