88 TII Timing Question.
Ok well i checked the timing today, and i put the light on the l1 wire first and the yellow mark was WAY off so I adjusted it to the pointer, and the car runs alot better in the upper rpms just idles high now, my question is well i put the light on the t1 wire and the red mark was way off too but if i adjust it to the pointer wont that thow the yellow mark off again? or am I not doing something right, or is something Not right with my car.
Help me out here....
Thanx guys and gals

It's too odd for words. I suggest you go drive the car and get it fuly hot, then try timing it.
Lead coil is the one near the battery. Both fire at the same time. Both go to the lower sparkplugs. So you can use either to check the Lead timing.
Make sure the TRAIL plug wires are going where they should. The T1 and T2 are embossed next to each of the top sparkplug holes plus look at the trail coil assy and you'll see the T1 and T2 embossed below the bores of the trail coil. Make sure they are going where they should.
The first mark that comes around when the pulley is turning is the lead mark and the second mark that comes around is the Trail mark. I've not a clue why your timing isn't showing up right except maybe the trail wires are in the wrong place or the engine isn't fully warmed up. Got me. Also the pulley might have been put on wrong. As in someone has wallowed out the four holes in the pulley at some time to make it fit. The stock pulley holes are offset so that the pulley fits the hub only one way..........unless you wallow the holes out to make it fit which in turn throws the timing marks off.

Ok so your saying that when i check the timing the yellow mark should line up with the pointer when im checking with the lead on L1, and then when I put my timing gun lead on T1 that the pointer should line up with the red mark? My original question is i adjusted the cas so that the yellow mark was lined up with the pointer while i had my lead on L1, BUT when i put my timing gun lead on T1 The red mark was way off the pointer, so as for my question if i adjust the red mark to line up with the pointer wont that mess up the yellow mark again, or to word different, if the pointer is set on the red mark at idle it cant be set on the yellow mark at idle right??? HOpe this is all clear

Bottom line I have not a clue why your lines don't align with the pointer. The best I can do is GUESS that you have maybe a series one carb pulley on a 13B car. The series one pulley has it's marks at TDC and then 20 degrees after TDC. That MIGHT be what is wrong with your car. Maybe not. I"m guessing. I've NEVER seen a problem like yours except one time where I put the timing gun on a very COLD engine. As in a forty degree outside air temp day.
IF you look at the Outut Devices Chart in the series five FSM, you'll see that when the engine is COLD, the Lead and Trail will both be at 5 degrees BTDC. I doubt that is your problem since it's not cold anywhere in the USA right now. BUT if it was cold, then the marks would both be off and although you might turn the cas to correct one, you'd never be able to get both right. It's just an observation and a FYI for the future for you. Most likely NOT your problem.
A misidentified pulley might very well be your problem. Or wires on wrong.
What say you get a six inch scale out and measure the distance b/t the two marks and reply???? Yes. Bend the scale to match the curve of the pulley for and accurate measurement.

So your saying that unless i have my trailing wires messed up that when the yellow mark is on with the leading when i switch the gun to the trailing that the red mark should line up also????
Ill try and messure the distance between the marks, wat should it be???
Will this hurt anything if i cant get them both to in up??

I used to have the same "problem". Checking it at the coil end of the plug wire gave me false results. Check the timing on the plug wire at the sparkplug end. When that works post back and I'll explain why.

the little clip that checks the plug wires needs to be as close to the engine as possible, and orientated right, otherwise it wont read the wires right.

Oh heck YES and that's your problem. Just above 1000rpm the ECU will by itself advance the timing above the 5ATDC and 20ATDC to somewhere ABOVE TDC..
You NEED to get the rpms below 1000 rpm and if I were you below 800 rpm. The stock tach on some cars is off 250 or more. Seen that on a car.
So don't do anytbing radical. Just get the rpms DOWN around8 800rpm or below,.

Ok well how else can i get the idle down, because i think my bac valve is shot cause it wont make the idle go down anymore, and if i test resistance across the terminals its giving me like 13.5, and the fsm says its supposed to be between, 10.7 and 12.3. Can I just turn the A/C on to make to idle go down or will that mess it up also? thanx
Is my bac valve bad>>
