Is there a way to un-plug the cats - or do you need to buy new ones ???

I agree with Rich D.

 I have seen this toooooo many times with European cars, if they run a can
of that injector fuel cleaner in the tank.  A few days later.. will idle
but no power or die when given any gas., plugged cats.

Well, it's probably incorrect plug wire positions on the distributor drive.
I assume this is a pre-1996 119 engine with dual distributors and coils
correct?  I doubt c

check after pulling the valve covers.



I'm betting that it's the position of the plug wires on the distributors.
Check those carefully against a diagram.  Note that some wires from the

wasn't done.

I Have posted the message on the R129 list but since I am not a member of
the R129 list I fear that my post will not get through. Those few who ha

transplanted the an M119 engine to their W126 SECs might be able to offer
an
insight.



Anyway, the problem is that my mechanic is working on a R129 that needed
a
valve job. After he refitted the heads back, the car in question has no
powe

the accelerator is floored ---- no power. I will be visiting him next week
to personally drive the car and see what could be the problem and to help
him do a bit of trouble shooti

A few things already in my mind are to go over the cam timing, correct plug
wire fixing and a compression test. Any other points that come to mind would
be welcome



Thanks in advance.
