B16A problem.
After I drive my car for a while say 20 minutes then my engine start to hesitate and then shut down especially when the temperature outside is hot and when the engine load is heavy (uphill). But after leave the engine off for 2-3 minutes and then the car can go for another 1km or so before it's start to hesitate again (even on flat road). Could it be the sensor (I don't know what it call) near the oil filter, looks like O2 sensor, with 2 cable (color yellow/green and black)? Anyone know? Please. Thanks.

No Cel light. No, I don't have SFC VTEC controller. I do have fuel pressure regulator and when it happen (also cannot idle normally before it shut down) the fuel pressure regulator showing stable pressure (32 psi),so it won't be the fuel pump isn't it?

I found out last time the coolant temp sensor (the one look like O2 sensor) was loose.But after I fixed it,the problem seems not going away.I also think it's about fuel/air/spark but this happen when it's hot and when the engine at heavy load usually.I change the sparkplug and doesn't solve the problem.My engine is 1st gen JDM B16A with PR3 ECU.The car was running fine for 6 months before this problem start a week ago.Anyone have different opinion? Thanks.

You could try testing your coolent sensor.....get an ohm meter and a pot of hot water...plug the ohm meter into the two wires on the coolent sensor read the sensor out of the water then stick it in the water the reading should be less then it was originaly if it is the same the temperature sensor is bad

Probably the best solution would be to go to a parts store and get a haynes maunual, it would give you a general idea how to test all of the sensors and what kinds of volt/ohm ages to look for.
