so ive had 2 cases of this weird problem idk if theyre related or not. First issue was the day i got the car i stopped at a car show on my way home and when i went to leave the car wouldnt go over 2000rpm and trying to would make the car bog down really bad but after about 5 minutes it ran just fine. The second time was after i had removed the air box to test fit an adapter plate to run a pod filter. I had removed everything after the afm, and once i had the plate all mocked up and ready for a filter i put the airbox back on but forgot to put the hose that goes to what looks like the ac compressor and i also didnt put back on the intake peice that goes over the radiator area. But when i went to go to get the pod filter from my friends house i had problems. The car drove just fine for about a minute but then would shut down about ever 20 seconds. Id start it up again it would run just fine and then i would take off and then it would just die, or i would turn it on let it idle and i would just die, weather i stayed in 1st stayed stationed at idle or tried to get into 2nd the car would die after a short time. I popped the hood and noticed that pipe going to the ac wasnt connected so i connected that and it didnt change anything. So i made my way back home. When i got home i reinstalled that other peice of the intake and it didnt help either. So i let the car sit for about 5 mins while pondering the problem and went back and the car ran just fine, nor probs at all. Anyone have any ideas? Cuz i dont want something like this to happen when im like 100 miles from home or anything. Its an 86 glx na

 

Check the water thermosensor.

 

Good idea it totally could be. Im also getting horrible gas milage at about 14 or 15 mpg

 

It wouldn't be a bad idea either if you took the voltage readings from the relevant ECU pins as stated in the FSM ( fuel and emissions control section).
