I got codes p0021 p0010 | was wondering specifically what the codes can be. I've seen a lot of timing chain issues. But my car lately hasn't been wanting to turn on and if it does turn on the rpm's are so low. Like the car is about to die from low rpm's but after a couple seconds rpm's go back to normal. Drives normal and everything I'm confused also It smell more gas from the exhaust so running richer maybe. I'm not to good with car stuff I've been trying to learn more. Please help me figure it out Also other codes if you want to know them let me know if they might be important. -P0051 -P1148 -P1168 -PO460 -PO158 -P0031 -P0051
