I've been trying to figure out why my car has been running like crap. Went and checked the timing today. It was at 15 degrees (spout connector unplugged). When revving it, it just stays at 15 degrees and is not advancing. What could be wrong?

First make sure the spout is getting good connection, check the 2 wires for damage. Not sure if I read it right but one website said you can test the spout connector wires and it should equal battery voltage. It says to test from the wire to the distributor base if that matters? Engine running at idle.

Spout connector was in and it wasn't advancing. Also notice another weird thing....it will sit and idle in neutral fine, then I push the clutch in and put it in in gear it revs up for a second and then idles a little higher than before. Do I just have all kinds of problems? ha
Dump the codes and see what the computer says is wrong…Codes may be present in the computer even if the Check Engine light isn’t on.
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. You watch the flashing test lamp or Check Engine Light and count the flashes.

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.
The STI has a gray connector shell and a white/red wire. It comes from the same bundle of wires as the self test connector.
89 through 95 cars have a working Check Engine light. Watch it instead of using a test lamp.

There is a single dark brown connector with a black/orange wire. It is the 12 volt power to the under the hood light. Do not jumper it to the computer test connector. If you do, you will damage the computer.
What to expect:
You should get a code 11 (two single flashes in succession). This says that the computer's internal workings are OK, and that the wiring to put the computer into diagnostic mode is good. No code 11 and you have some wiring problems.
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.
Alternate methods:
For those who are intimidated by all the wires & connections, see Actron® for what a typical hand scanner looks like. Normal retail price is about $30 or so at AutoZone or Wal-Mart.
Or for a nicer scanner see Equus - Digital Ford Code Reader (3145) – It has a 3 digit LCD display so that you don’t have to count flashes or beeps.. Cost is $30.
See the "Surging Idle Checklist for help with all your idle/stall problems. Everything you need to find and fix idle problems is in there.
The first two posts contain all the updates to the fixes. At last count there were 24 possible causes and fixes for surging idle/stall problems. I continue to update it as more people post fixes or ask questions.

I would check the the sprout to make sure it is a jumper it could be open which will not let the computer control the advance.
Ok, I just tried this with a test light and jumper wire. The light on the test light is kind of dim with the key and gets bright with the key on but does not blink any. Do I have some major problems?
This thing still barely has any fuel pressure according to the gauge. I'm going to try a new fuel filter tomorrow and go from there =(
