Hi guys im new to the forum and hopefully someone out here can help me with an issue i am encountering.
I have an 87 gt convertible which stalls completely off except for the lights/stereo
The weird thing is, if i get out the car, it suddenly stops.
Theres time while i drive it and it stalls but it starts right up again, by itself.
The car still turns on every time though
Im hoping someone has had this same issue because no codes come up either
Thank you guys!

Welcome Luis. I don't undertsand your description. Would you explain a little better.

stalls completely off except for the lights/stereo- nothng else works?
The weird thing is, if i get out the car, it suddenly stops.- what stops. the car or the stalling
Theres time while i drive it and it stalls but it starts right up again, by itself.- the car stalls, stops, and then starts back up? is the key on or off.

When you ran the codes did you get any codes at all . Code 11?

Sorry about that, i was in a rush while writing it.
Well when the car stalls, all the electrical components work
When driving it sometimes stalls for about 5 seconds but starts right back up by itself, with the key in the on position.
When it stalls and i come to a complete stop the car turns on without any hesitation at all.
When the car is in park and i get out the car, the engine shuts off but.the electrical components stay on.
No codes at all, thats what a shop told me
The car is an automatic
Thanks for your input

No code for VSS or TFI? Tach, instrument lights, and windows all work fine? Did you check your grounds as those can play havoc with your car. check your ignition switch- located on the bottom of the steering wheel. With the car running. pull the small purple wire off the S terminal on the starter solenoid on the driver firewall... If the car keeps running the ignition switch is bad.

Whoah. you forgot to mention that. That could be your problem right there. If the wires are fried or loose, you need to address that. Someone make a replacement wire kit but I can't remember who. If that is the case, get it repaired asap as it's a fire waiting to happen.

Any auto parts store has them. You'll need a torx bit to remove it. Disconnect the battery first.

Here's a video to show you how
