I replaced the map sensor. There was no improvement in the vehicle.
I purchased a throttle set. Same brand original same code.
The car got worse when I installed a new throttle valve. It started to stop completely.
I reinstalled the old throttle.
I rechecked the spark plug ignitions and they all fired very well. The resistance of pipe cables is around 0.7k.
I tested each injector separately with the ODB testing machine, it sends fuel and cuts it off.
I have no idea where to look now.
Compression is already good.
But this all happened after the car overheated. The car was running smoothly until that day.
The vehicle makes exhaust noise while operating.
both at idle and when I give gas. Exhaust rumbles constantly. I think this means it can't burn fuel or burns it late.
In this case, I don't know whether to look for the problem in electronics or mechanics, I focused entirely on electronics.
Note, I have been trying to repair my car for about 1.5 months and I cannot drive it. It will probably continue like this for another month
Note 2 : There was a slight code difference in the map sensor I installed. The seller said it would be compatible.
