[W126 Coupe] running rich

[Attila]

        The best advice I have is to lean-out the engine a full

        half turn.  This is what I needed to do, after I changed 

the entire exhaust system.  It now takes 3 short tries 

to fire it up, but no more black residue in the tail-pipes,

all grey.  Performance has not been affected, at all, and

if you don't like it, you can always turn it back, following

the inspection.  Of course, if the leak is too large, playing

with the tower may not solve the problem.  If it is the 

large boot on top, you may be able to seal it temporarily

with tape/glue.  If it is one of, or multiples of, the eight 

rings between the manifolds, you can change these yourself,

but it's time-consuming.  Are you using premium grade

fuel??  Try some aviation fuel, 1/3 max to full tank.  Burns

very clean.  Just make certain that the cooling system 

works perfectly.

Hi Guy's

It's Clay again still playing w/the  88 560 couldn't pass emissions too
rich. Took to have ajusted on machince at M/B service and they told me it
was a leaky intake manifold, and wanted $1600.00 to fix it. I almost dropped
to my knees because another mech. I've had some work done by told me it was
listed as 6 hr. job. He said $600.00 unless he had problems w/bolts snapping
of and then it depened on time. I once had a 88 560 sel and it was not
passing and a different guy put a BB in the hose of the map sensor and it
passed perfect, but can't remenber if that one was running rich or lean. But
when they opened the hood for that fume test the tester squeezed the map
hose to check. Any Ideas on what I should do w/ this car, all health
problems I've had, have had me on my back for alittle of 9 Months and can't
even walk over 20 ft. 

I broken the same ankle 3 times in the past year because of the leg giving
out. Couldn't have invasof Surgery because of comidin for heart. I was just
thinking of getting rid of it as, and eating the loss.

Thanks,

Clayton Moizo
