Help Door adjar car stalling while at speed!!
HI All i just joined forum and would like to say hello first!
I have a 76 corvette and 6 months back i started seeing a flashing then steady door adjar warning light. I would get in car at random after driving and could not start. After running around the car like a chicken with its head cut off i would get back in and it was fine.
I started feeling it was the door slamming that was making it better so I replaced drivers door switch and took it for a ride and the car stalled 3 times at 30mph and back fired so i pulled out the switch and she made it home fine.
I re did the switch and she drove fine for a few days then sat a week and the door adjar came back on and she stalled again while at speed.
now i figured out the passenger side door is also now tripping the warning light.
so I will replace.
My question is could these switches be tripping a kill switch to actually kill the car while driving?
Thanks

Never heard of such a thing.
My guess is that (if) you have an alarm system that was messed with at some point it may be "bubba'd enough" that the door adjar is cutting off the ignition.

I don't even see an alarm other than the lock on the hood.
Something else I did was put headers on it and I started thinking there was a heat issue with the starter. I then wrapped the header near the starter with heat tape and am wondering if that is causing some kind of short but those are the only 2 things I messed with and the car drove fine the first year I had it untill door adjar lights came on steady.
lastly when dealing with the switch on drivers door rear I found a ground wire from the pillar leading to switch in addition to the 2 connected and it was not attached to anything I'm thinking it went to the switch holder plate originally so I was not that worried it was no longer grounded.
This is a real pain very scary i would not take this car very far or go on a highway the thing is after the stall she starts right up???

The door ajar system only tells you if either door is not closed well. It does not affect driving or the anti-theft system.
The door ajar switches are the short ones on the jambs at the rear of the doors; one on each side.

yes Im feeling the door ajar could just be happening at the same time as some other problem and throwing me of track.
Does any one have any thoughts on what could cause a car driving fine for about 10 minutes at 30 mph to just die? I always have just enough umpf to steer it off the road then it makes a horrible back fire and is completely shut down untill i turn the key again to restart and she starts.
this originally manifested as a drive for a half hour then get in the car after shopping and no start. Wiggle key nothing, slam doors wait 10 mins she would start again now its changed to stalling while driving.

I wrapped the header on the passenger side only thinking the random no starts were from the heat of header screwing with the starter. now I think the wrap with a chrome outside is grounding out the starter or a plug BUT would that be enough to stop a car dead at 30 mph?
I have a sheild on the starter but its close to the wrap. Last I looked wires to starter were good but i will need to take another look since i did the wrap.

You clearly have something wrong in your ignition system. My guess is that something is loose and road vibrations cause a loss of contact.

My guess is that you have something loose under your dash as your car seems to start and run at a stand still, slamming doors "make a difference" and that driving creates a vibration.
Do you have a shop manual? You can easily trace all your ignition stuff under the dash.

Yes, absolutely the right place to start but you also need to check your distributor, coil, connections under dash.... etc.

It could be the ignition switch down under the steering column.
Try rotating the key a small amount within the run notch and see if it shuts down or comes back alive after it has shut down.
Try hot wiring directly to the coil and see if it stops shutting down.
