Hi guys,

I have a 1986  Euro 500 SEC with 238,087 miles; my car runs well and it has 
not been abused,  but it burns some oil and runs too rich. In the morning 
when I try to start  the car, it will not start unless I press on the gas 
paddle or attempt to  start it two times...

I'm thinking of replacing the cold start switch.  What would you recommend? 
Also is there an electronic device (computer) that  regulates the idle and 
fuel mixture?

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
