help on timing

[stangboy575]

i just put a mild cam and gt40p heads on with a bucnh of other things...now i want to time it and its giving me trouble...i just got a timing gun and timed it to 10 and it runs like crap...then i tried setting it to 14 and it still runs like crap....and it also spudders while in gear..im running out of ideas..give me a hand if possible

Putting the distributor back in is fairly simple. Pull #1 sparkplug, put your finger in the sparkplug hole,
crank the engine until you feel compression. Then line up the TDC mark on the balancer with the pointer
on the engine block.

The distributor starts out with the #1 plug wire lined up at about 12:00 with you facing it. Align the rotor
to about 11:00, since it will turn clockwise as it slides into place.

Align the distributor rotor up with the #1 position marked on the cap, slide the distributor down into the block,
(you may have to wiggle the rotor slightly to get the gear to engage) and then note where the rotor is pointing.
If it still lines up with #1 position on the cap, install the clamp and bolt. If not, pull it out and turn 1 tooth forwards
or backwards and try again. Put the #1 spark plug back in and tighten it down, put the clamp on the distributor,
but don't tighten it too much, as you will have to move the distributor to set the timing. Note that if it doesn't
align perfectly with #1 position, you can turn the distributor until it does. The only problem is that if you are too
far one way or the other, you can't turn the distributor enough to get the 10-14 degree optimum timing range.

10 degrees BTC is towards the drivers side marks.

Simplified diagram of what it looks like. Not all the marks are shown for ease of viewing.

ATC ' ' ' ' ' ' ' ' ' '!' ' ' ' ' ' ' ' ' ' BTC
---------------- > Direction of Rotation

The ' is 2 degrees.
The ! is TDC
The ' is 10 degrees BTC
Set the timing 5 marks BTC. Or if you prefer, 5 marks towards the driver's side.

At this point hook up all the wires, get out the timing light and start the engine. Set the timing where your car
runs best. Don't forget to disconnect the SPOUT jumper connector when you set the timing, and plug it back
in when you finish.

The HO firing order is 1-3-7-2-6-5-4-8.
Non HO firing order is 1-5-4-2-6-3-7-8

i did all that and it does nothin

i had that problem n yah you gota take the number one spark plug out like said before and crank it for a second at a time then when it pushes ur fingure out then make sure its tdc as far up as you can get it before it goes back down then the rotor in the distributor on the number one plug wire if it still does it then makes sure ur firing order is rite

 

[stangboy575]

firing oder is right...i checked it a few times...u think the distributer is bad n thats whats causin it to run like crap

 

[BYRDPE]

you changing timing with the spout out correct?

Dumping The computer diagnostic codes on 86-95 Mustangs

Revised 19-May-2009 to update drawing for dumping the codes on 86-88 Mustangs with no check engine light.

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 way 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.

Be sure to turn off the A/C, and put the transmission in neutral when dumping the codes. Fail to do this and you will generate a code 67 and not be able to dump the Engine Running codes.

Dumping the Engine Running codes: The procedure is the same, you start the engine with the test jumper in place. Be sure the A/C is off and the transmission is in neutral. You'll get an 11, then a 4 and the engine will speed up to do the EGR test. After the engine speed decreases back to idle, it will dump the engine running codes.

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.

See Troublcodes.net Trouble Codes OBD & OBD2 Trouble Codes and Technical info & Tool Store. By BAT Auto Technical

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.

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.


WARNING!!! 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 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.



A bad distributor will often set a code 14

Won't start unless drastically retarded

My #1 piston is all the way up on compression mode. the rotor points to #1. The damper mark shows TDC +10. When I crank, the timing light indicates TDC +10. But it won't start. If I move the distributor counter clockwise--retarding it--pretty far, the engine will start, but not run well. What is going on? It seems the damper is in correct position on the crank given the #1 piston is all the way up.

I think you might of indexed the cam when putting the timming chain set up on?peace

pull the timing cover and make sure the cam is in right. almost willing to bet its 180 out

 

[globaltefl]

That could explain the other mark that someone put on the damper way over to the right of TDC. The engine was swapped out before I bought the car. So now what do I need to do?

turn the cam 180*

 

[Mustang5L5]

What are the "bunch of other things " that you installed?

What yea car and engine? You said the motor was swapped out? From what?

 

[globaltefl]

The car starts! That mark on the balancer at about 50 degrees advanced apparently had to do with the cam being degreed. I put the indicator on that mark and the rotor on #1 and it started right up. But when I put the SPOUT back in it didn't run so well. I guess I am wondering about the advantages of cam degreeing? Should I go in and reset the cam on TDC? How can I get it to run better degreed and with the SPOUT in?
