So after I warm up my 87 na it idle at 400 to 700rpm it sound like the tips but I do t know what that is ?
And it over heats and sat for 3 years and I did all the basics to it.

Just another problem. It dousnt help learning how to Sri e a stick lol so easy to stall when warm

 

Has it always done this or did it just happen one day? Open the air bleed a little or adjust the idle screw. That alone will probably solve your problem. You may have a bad idle control valve. By tips do you mean tps? The throttle position sensor wont cause a low idle. Most likely just need to turn up the idle or check the bacv

 

Ill try that and see what happens
