NISSAN 200SX SPARK PROBLEM

1980 Nissan 200SX

1980 Nissan 200SX 4 cyl

hi my name is pedro and I got a 1980 nissan 200sx 4 cylinders and the car starts ok and runs ok for the first 5 minuts in the morning or wen the engine is cool. After 5 minuts runing you step on the acelerator and the car start missing like no gas or spark. But the car has good spark all time and the gas pressure is around 35 / 40 psi. I'm thinking in the coolant temp sensor but i'm not shure or if can be something else. Aprecceate your help. Thanks.

Engine running rough or misfiring can be cause by the following: 1. Defective spark plug
2. Inadequate spark/coil, defective spark plug wire.
3. Lack of compression
4. False air leakage.
5. Faulty fuel injectors.
6. Insufficient fuel pressure.
7. Contaminated fuel.
8. EGR valve that is leaking.
9. Oxygen sensors.
10. Throttle position sensor.
11. Idle air control valve.
