I have an 86 GT, I bought it with a really bad clutch, replaced it by pulling the motor and trans like you should. I do have a check engine light on for the O2 sense, When I am driving and the car is still somewhat cold it runs ok, but after it warms up and I am driving it will just dye, but with it in gear, I can down shift it and "jump start it" as I am rolling and it will back fire every so often. I wouldn't really care so much but I am driving it to work and its really cold out and its going to be a few more weeks before I install the N*. Any ideas?

Just about any of the sensors can cause this once the car warms up and starts reading input from the sensors.
If you have a code in your ECM, it's always a good idea to address that first. Chances are if your O2 sensor is more than a couple years old, it's bad. I'd start with replacing the sensor even though the code could be a symptom from something else.
My car did the exact same thing! I have an 85 GT auto that would want to die in gear when close to idle. when idleing in neutral or park it would run just fine. i was told that it could either be the sensors (mainly the O2, or temp) or it could be the ignition system. i ended up replacing all the sensors and the ignition system at the same time. ever since then my car has run fine. if you car has the same problem that mine did then i would recomend checking out those two options. hope they work.

Do check this, crank the engine and watch your tach. If it don't start and your tach didn't move while cranking, unplug and reseat the connectors on the distrib. They can be very intermitant. If you're not getting tach pulses then you're not getting spark either. If that don't get your tach to move, remove the distrib cap and make sure you did not pinch any wires inside the last time you put the cap on. Good luck.

Ignition modules aren't that hard to find just lift the cap and take out the 2 little screws. I can do that with my eyes closed. When you check the spark, watch the color. Sometimes a weak coil or coil pac will spark but it will be yellow instead of electric blue. That has fooled a few people into thinking the spark is okay.

I thought I would finish this thread, I replaced the mod. under the rad. cap and that didn't work, replaced the fuel filter and that didn't work, I replaced the coil and ign pick up under the cap and so far so good. Just to let you all know or those of you that haven't had to change the pick up ring under the dist. cap, heres how you do it. 1. Remove the coil and move it over, that gives you alot more room, and to do so there are 2 13mm bolt type screws that held mine down. 2. make a mark on the dist. shaft and on the block so you have the location marked where it was so it can be placed back in the same location. 3. Remove the singal bolt on the intake 4. Remove the dist. cap 5. NOTE, where the black plactic rotor is pointing 6. Remove the dist. by pulling straight up and it helps if you turn it back and forth alittle 7. pull off the black rotor 8. then there are three spots that look like they maybe allen screws covered in oil, they are not, the top two are one push pin type thing. it needs to be punched out and removed. 9. Then remove the bottom part under the gear and remove the gear and washer, plus there is a thick type washer with some little folfs sticking up, watch where it is so you know whee to put it back and how it was, you can really see it before you pull it all apart. 10. from the top pull the shaft out 11. pry off the old squire type ring that hold it on, and unplug it 12 pull off the old plastic pick up 13. replace it with the new one and be sure to line up the two little taps on the bottom 14. plug it in to the ign. mod 15. put on and line up the new retainer ring and pop it on using a little larger socket than the top of the shaft NOTE not to hard 16. put the shaft back in, infact the install is just doing everything backwards, just besure you line it up the way it came out!

Isn't PFF great, a few weeks ago you couldn't even find the Ignition Module, today you're telling people how to repair the distributor.

Ok. So how do I get the oxygen sensor out? I bought one but I can't get a wrench on the old one so that I can turn it. Since it didn't turn EASY, I don't want to strip it.

I spent $12 and got a O2 senser socket, mine came out without to much trouble, it get alittle warm driving it into the garage. Or just cut off the old wire coming out and use a reg. socket. If it still doesn't come out warm it up with a small torch and then pure on some warm water, thats how I removed the 3 freeze plugs on the small block Chevy blocks?

by the way I need a torque rod do you sell them separately from the kit and how much.
