sometimes while im driving my car will start to hisitate and bog and ecu codes 3, 7, and 23 will pop up and the engine would run lean. and if i turn the car off and try to start it itll die rite after it starts. if i unplug the map sensor the car will start but run rich and doesnt drive normal but still drives and the same 3 codes pop up. anybody know wuts the problem? i was thinking a new throttle body with the sensors could fix this problem but i dont wanna buy it and find out it doesnt fix it. also i think it could be the ignitor but y would those 3 codes pop up? thanx for any help.
