So three weeks ago i bought an 05 Mustang. Today i pull into the gas station with it, leave it running when i got out and was talkin to someone i knew. All the sudden the rpm's dropped down to around 200. i didnt think it sounded right so i got in and turned it off, then tried to turn it back on. It started up, putted a bit then shut off. i plugged in my computer and it came up with three codes : P0183 , P0191 , P0193 . It had something to do with the fuel pressure i have it written down in my car....but i just pushed it seven blocks,came home and forgot the paper i wrote everything on in my car i jus know these are the codes. So any Feedback would be appreciated...Thanks
