Hey guys need some help maybe someone had this problem before. My car recently started acting up on me, It will drive fine i can go to a store and it will be good, as soon as i restart the engine driving back 2 minutes later my engine will get louder and RPM will go up to 1.5 along with check engine light comes on. This is where it gets stupid, as soon as i give gas the RPM will jump up and down and its almost impossible to drive, and every time i switch gears its very rough almost feels like the engine drops. I can pull over and reset the ECU and it will be fine again, but as soon as the car gets restarted it will do same thing, every time i make a stop i have to reset the ecu.
