IICR is a part #?
Also, the plastic lines behind the passenger shock mount... Are those
vacuum lines?
There are a few different colors, one goes to something on the intake..
Well one of the white ones is broken... How can I fix a plastic line???
BTW thanks for the help.
How to pass emissions testing:
1.) Make sure all the emissions gear the car was made with is present and
connected up properly. That includes a working smog pump and cats.
2.) Make sure that you have fresh tune up with spark plugs, plug wires, cap,
rotor, fuel & air filters. An oil & filter change is a good idea while you are at it.
3.) Dump the codes and see what the computer says is wrong…
Here's the link to dump the computer codes with only a jumper wire or paper
clip and the check engine light, or test light or voltmeter. I’ve used it for
years, and it works great.

OR
See

IF your car is an 86-88 stang, you'll have to use the test lamp or voltmeter
method. There is no functional check engine light on the 86-88's except
possibly the Cali Mass Air cars.
Codes have different answers if the engine is running from the answers that
it has when the engine isn't running. It helps a lot to know if you had the
engine running when you ran the test.
Trouble codes are either 2 digit or 3 digit, there are no cars that use both 2
digit codes and 3 digit codes.
For those who are intimidated by all the wires & connections,
see
http://www.actron.com/product_detail.php?pid=16153
for what a typical hand scanner looks like. Normal retail price is about $30 or
so at AutoZone or Walmart.
Or for a nicer scanner see
http://www.midwayautosupply.com/det...iption.asp?3829 – It has a 3
digit LCD display so that you don’t have to count flashes or beeps.. Cost is
$33.
4.) Post the codes and get help to fix them. Don’t try to pass with codes not
fixed. Clearing the computer just temporarily removes them from memory, it
doesn’t fix the problem that caused the code to be set.
5.) Be sure to do the testing on a hot engine. Drive for 15-20 minutes prior to
taking the test to get operating temps up into the normal range. Do not shut
off the engine while waiting for your turn on the test machine. An engine up
to full operating temperature puts out fewer emissions.
The maze of colored snakes on the passenger side strut tower are the
vacuum lines that work the emissions gear. You patch plastic lines by splicing
in the proper size rubber hose between the broken parts.
The white line operates the EGR valve.
