Went out to start my car today to go to work... wouldn't start... as I'm turning the key, the motor is trying to turn over but won't and as I’m trying to start it's backfiring like crazy~! For the past 2-3 weeks it's been throwing a code 43 which is a problem with he fuel supply system or o2 sensor... and before I could start the car right up and it drove great until the motor would warm up, then the check engine light would come on and the car would start to hesitate, back fire... just run like shit.. I did manage to get it started today for a little bit, it idled ok but when I put it in gear to move it, the car died.. Also, when it was in neutral it would back fire like crazy if I touched the throttle.. My new o2 sensor is on order and is supposed to be here tomorrow morning ... ordered one earlier, took a week to get and it was the wrong one, was an o2 for a 2.0 si prelude not the 2.3L si... but anyway, I checked the spark plugs which are 2-3 weeks old and they are black ... so I put new ones in... Still no luck starting the car.. So if anyone has any ideas, please feel free to let me know. Anything I can check or whatever. Thanks! Reply here or hit me up on AIM: Miiiiiikkkee. Thanks to any/all who help~!
