[DeTomaso] Engine help needed - I've got gas! (or my car does....)

Sun Nov 13 21:20:10 EST 2016

I have them tell me when it almost my turn and run the car around he block in first gear so it can then go into the test bay

OK, thanks. It's very helpful to understand the theory - now I have a
problem in applying it. I have a nice, 20 minute highway drive to the
testing station, but the only way to reach the sniffer is to get in
line and wait.

Yesterday was very frustrating - typically the wait is 10-15 minutes,
and I don't know what happened yesterday but the wait was horrible. I
knew that a cold engine was a problem so I kept the engine running.
It's cold here in November, and 45 minutes with the engine shut off
would mean a fairly cold block.

I wonder which is worse - shutting the engine off (cold engine but
without all the carbon/etc) or letting it idle (warm engine but carbon)

The wait isn't something I can control. Would just revving the heck out
of the engine before entering the test bay help blow the cobwebs out?

No Charlie, you misunderstand...

An engine IDLED for 45 minutes is nearly guaranteed to FAIL. It will
be so loaded with carbon it can't possibly pass, no matter how "warmed
up it is."

You need to be DRIVING it for 45 minutes and immediately test it. It
needs to be taken through the gears, engine rpms taken high,..... Blow
out the cobwebs, the carbon build-up, etc. Then test. If you idle for
any length of time waiting in line... rinse and repeat. Do NOT spend
time idling in line, it will kill your test.

Thank you to all who answered.
I understand that a warm engine will contaminate less. The car was
literally
idling for 45 minutes before testing, albeit in 45F ambient
temperatures, so
I think it was properly warmed up. Due to the lines and waiting, it
would be
difficult to come off the highway and roll right into a test bay, but I
can
let it idle for as long as I'd like before entering the bay. The lines
tend
to be pretty long where I go anyway...
I understand that higher rpms will reduce contamination, and therefore
we
should all drive faster to save the planet! I'll raise the rpm a little
for
the test.
I'm reluctant to fiddle with leaning out the idle or playing with the
timing
- neither have been touched since previous years so I have to believe
that
the current settings can work.
I'm also cautiously optimistic that the air filter is really, really
clogged. I've spent a weekend camping at Le Mans Classic in the dust,
driven
down a 2,5 km dirt road a bunch of times in Denmark, etc etc. Tomorrow
it's
supposed to be nice so I'll drive around the block with the air cleaner
removed and see if I notice any difference. If it's clogged enough to
make
me fail emissions, maybe I'll notice something with the
seat-of-the-pants-o-meter.
Thanks again!

Also, make sure the engine is good and hot (not overheating). Take it
for a good long spirited drive and then immediately have the emissions
tested. If the line is too long... come back again later. You get
better test results when it's been running good and hot for a while.
