Hi Luther,
Nope - zero carbon buildup - when I changed the GPs I was prepared with
a reamer to clean any out needing it - none had any carbon build up. Of
course, for the last 8 months I've been running a heavy duty cylinder head
treatment to remove all the carbon - called Ferox 230. It corrected a cold
running problem I had and as far as I can tell it completely cleaned the
carbon from the head.
Anyway - thanks for the help --
;-)

is there any carbon build up around the GP's? That will kill a GP
quick..... You might need to ream out. I used several old GP's and
flattened them with a hammer and run them down tight to scrape out the
carbon.

Howdy -
I replaced my GPs and the GP relay within the past 3 weeks or so.
Yesterday, the preglow light came on for only a second or less - even
though
it was in the upper 40s and hadn't been started since the night before -
it
was stone cold - it started instantly although it runs like one cylinder
isn;t firing evenly. Within a minute the engine idles & runs smoothly.
I'm wondering about the possibility of a GP being bad out of the box?
Also - is there a way to check each GP without removing them - it's a
PITA
on a 1991 300D 2.5T. ;-) Don't know how successful I'll be but I plan
to
see if I can wiggle my hand past all the in the way to see if I can
detect
any loose wires.
The GP's seem to be pretty basic - but I guess the innards could be bad
in
one.
BTW, everything on this car looks to be in perfect condition - all the
wiring looks new with no corrosion - there's only 114k on this car.
Thx -
