Marshall,
Is this description of an 87 300D similar to what I should look at on my
91 300D. I'd like to confirm the line you described is clean on my 91 300D
and your description seems very precise, i.e. the Pressure line clogs.
All of the same issues apply, but your engine is more complex. If your
engine senses that the EGR is NOT working as it should, it defeats all
fuel enrichment the ALDA might request and the engine reverts to the
power of a naturally aspirated 602 engine (~90 vs 120 hp when the
turbo/EGR/ALDA are working as they should).
When everything is correct the 0-62 mph acceleration should be ABOUT 13
sec and if the ALDA/turbo/EGR system is misbehaving the acceleration
could be expected to drop to at least 16 sec and maybe a bit more than that.
