This was a very strange feeling as the engine felt weird as i drove off thinking it would help but it didnt. As i took off in first the car struggled to gain power i got the rpm up to 3k and thats when l shifted into second but when i shifted into second the car lost alot of power to were l had to almost push the gas pedal half way to keep the car running. l shifted into third at 2500 rpm but the car suddenly started dieing on me with very nasty jumping in the engine so i quickly pulled over and turned off my car. l let the car sit for about 5 min after turning it on again. There was no change to the car the engine kept jumping lighty with the rpms still jumping between 500 and 1000. This felt like Limp mode but the engine was struggling to stay on i had no choice but to drive it for another 4 blocks as i was close to my house. the whole way there the car was not letting me pass third gear because it would die on me if i entered third. When i got home and parked i put it into neutral and sudddenly the car started deing on me so i revved the engine slightly and the car backed fired about 2-3 times very loud and after that the car died while the engine shaked very hard. After this the car didnt want to turn on anymore its been 4 days since this incident. l scanned the car and gave me the code P0300 which is multiple misfires detected. There was also the code P2A03 which is the A/F sensor. l went ahead and took off all my spark plugs to see which one could be causing the problem. Piston 2 spark plug had oil but only on the body no where else. the rest of the spark plugs were clean and still good to use. But i went ahead and swithed them all either way. After all of this the car still didnt want to turn on. It sounds better now when i try to turn it on compared to the night when it died on me when i parked. I scanned the computer again and the P0300 code was no longer popping up but now it gave me 12 codes which is very scary the following codes are (P0223, P0123 TWICE, P2133 3X, P0228 3X, P0223, P0123, P2A03, P2101) . Any suggestion on how i could get my car to turn on again. My fuel pump works as i turn the vehicle to "ON". The battery is good as well. Thank you to who ever read all of this anything helps this is my daily so i need it ASAP.
