Well heres the situation. Recently, after the a rebuilt tranny, the car hasnt been up to par! It has been running really really rich. It has also been missing/cutting out at high rpms that is 3k and above. So today i took it to advance to have a scan tool ran on it. Heres is what it turned up:

1) Code 11 Malfunction Indicator Lamp Circuit Problem

2) Code 23 Manifold Air Temp (MAT) Sensor Signal Too Low

3) Code 42 Ign System Problem Elec Spark Timing (EST) Is Grounded

4) Code 48 Mass Air Flow (MAF) Circuit Problem

5) Code 64 Right Oxygen Sensor (Bank 1) Lean Exhaust Indication

And i did some research:

1) Code 11 Malfunction indicator lamp circuit voltage was wrong for 26 seconds.

2) Code 23 Inlet air temp sensor signal showed an air temp below -31 F for 60 seconds after the engine has been running for 4 mins.

3) Code 42 PCM did not detect any EST signal within 84 crankshaft revolutions.

4) Code 48 There was no MAF signal when the engine was on.

5) Code 64 Right oxygen sensor voltage was below 0.2 volts for 50 seconds of closed loop operation.

Any help of sorting this out would be greatly appreciated!
