You can get a clue, or for five hundred dollars, I'll give you what's
behind curtain number one!

Ok, I've been doing some research, and see the next thing to test is
the pressure switch. I've seen some sites that say it should read 24v
across the terminals when the correct negative pressure it reached.
Can
I get a clue where the switch is located?

Not really. There are many variables to the sequence of operation of
your furnace, that you need to check.

You can keep on changing parts, until you find out what it is that is
causing the problem, and even after you have replaced everything in the
furnace, you might still have the same problem.

I would call a pro, since furnace repair is really not a DIY repair.

If it was a newer furnace (don't know about 1987 features) I'd first
check that the air filter (cold air return) isn't clogged, check that
if high efficency the outside air intake/exhaust aren't blocked. And
you might try moving the ignitor a tad closer to the flame ... worked
for me with an older gas furnace.

Just keep throwing parts at it and listening to bogus advice from
newsgroups and you'll eventually fix it.
