[DeTomaso] 302 diagnosis

OK, then I would look at the carb.  It sounds like when the choke is on the 
engine runs well.

So, IS THERE a choke?  Electric or manual, (or none)?

It could just be running lean under warm/normal operations...

The cam and lifters are new and the break in seems to have gone well.  The
engine runs like a champ until it warms up although the vacuum always seems
low.  It runs great until it reaches normal running temperature, then the
idle starts to drop until it dies.  If throttle is applied, the engine will
continue to run well but not idle.  It will start easily after it dies.  I
had the motor out because I was having problems with the engine dying during
drives.  I had thought it was the timing chain and replaced that as the old
one was worn and stretched.  While the engine was out, I replace all of the
gaskets including the head gaskets.  The bores looked in really good shape
with almost no ridge.  The heads also looked good so I only changed the
valve seals.  The engine has 24,000 original miles on it.  No exhaust
popping or backfiring.  The motor runs really good until it is warmed up.
Starts right up and idles great even when cold.

Thanks,

Dennis
