Throttle body: $75 TO $250 on car-part.com for a 94 w/o traction
control. You have to know the engine number. There is a break about
10,000. Chances are that you will get one that has been replaced and
has good insulation. You can look at it before you put it on. Time vs
money. For $1000, you can have a known good one. For $75, you might
have to send it back and try another.
I try to keep enough cars that I can afford the time and save the $$$$.

There is only one way to check the insulation on the throttle body
harness, and thatâs to split the jacket and check the individual
conductors. The outer jacket was made with rubber, not the same
material the wire insulation was made with. Therefore, it will look
just fine from the outside. If itâs the original throttle body, I
would almost guarantee the insulation in the wires inside that harness
have turned to dust and the bare wires are exposed. Have Herbert split
the jacket a few inches and take a look. You can always seal it back
up with high quality tape.
It certainly makes sense if someone was moving things around in the
engine compartment - the harness to the throttle body is pretty
substantial and could easily be moved or bumped if things were being
cleaned.
BBA has good reviews. I canât vouch for anyone else, but when youâre
talking about a car thatâs worth a few thousand and a part thatâs
$1000 new versus a $500 rebuilt part with a 1 year guarantee (same as
youâll get for the new one) I would roll the dice and go for the $500.

Yes of course the photos lie and it has a few scratches but otherwise is a
very nice, lowish miles car.
Nobody can figure out any other reason why it should work fine and then
mysteriously develop actuator issues right before they put it on the
truck.
Herbert says he has had spotty luck with the throttle body rebuilders.
The harness is an obvious potential culprit if the insulation is
flaky. But
it seems ok.

You bought that great looking blue E420? The one with the parchment
interior? They washed the engine and now it has big problems?

So I bought that low miles 1994 e420 from Jeremy and Co up in SF.
Figured I
need the car and they said it drove well and was in good shape, and that's
about all I need in a 420. Paid and they sent the car.
It arrived yesterday. Started, backed off trailer fine. It was about
8am so
I hopped in it and attempted to drive to work. Unfortunately, it would rev
to about 1500rpm and stall, and repeat the sequence about every second or
so. It idles as smooth as silk, just won't throttle up. No lights on the
dash. Never got out of first gear or above 20mph. Not good news!
Called tow
truck, then Lyft.
Herbert the German mechanic says the fault code is either the throttle
body
actuator or the computer that controls it. He says the throttle body
is not
opening properly in response to pedal input. He asks if there has ever
been
water on the engine. I say not to my knowledge. He is still sorting out
what exactly is failing. Either one is a spendy item apparently; 1500 for
the actuator and lord knows if a computer would even be available. Herbert
himself isn't cheap either, but he knows mercedes.
So I got Jeremy on the phone and relayed this info. He apparently drove it
for several days and to the smog place before listing it, and it was
completely fine including the dyno test at smog. He says they did detail
the engine after that though.
So here is the question: what stuff typically gets messed up when you wash
an e420 motor that can cause this sort of thing? I am still hoping for an
outside chance of something simple, and I figured I would see if there is
any collective wisdom on this topic.
Thanks,
Karl
