Hello,
Using the helpfull documentation here on Prime, I have just pulled 2 codes from my ECU. The first is 3 long blinks and 4 short blinks. I'm not sure what this code means. The second code that comes up is four long blinks and 4 short blinks. I'm guessing this is a code for #44 - Rear Fuel Supply system.
Can anyone tell me if I'm reading the codes correctly. Also, if it is code #44, what could be the problem with the Rear Fuel Supply system.

Thank you for your help in advance.
 
a code 44 is either a rear O2 sensor and/or a rear fuel supply problem. We may be able to discard the fuel supply problem. So a question: does your car idle rough?
 
The engine light came on, so I checked the codes. The engine seams to be running fine. The only problem I see is the redline comes on around 7300.
