Can someone read these codes for me please?

I'm haveing trouble when my car is running with the A/C on sometimes when I'm downshifting the RPM's go way down with the volts and sometimes it dies so I pulled these codes off the car today. Battery and Alternator are new so can you read these. 34,67,10,11 All these came off the car but I don't know where the stupid book is to find out what each of them are. Thanks in advance!

No such thing as 10......11 is system pass......67 is neutral drive switch open or AC on...and 34 is EVP voltage above closed limit....disconnect the battery for 5 mins to clear the memory then run the codes again b/c there is no 10 and 11 is system pass at the end.

OK I left the battery disconnected and these are the codes that read out when I tried it again... 34,67, these flashed twice then 10,15 came up... What is wrong?

Codes

10 There is no code 10

15 (O) No Keep Alive Memory power to PCM pin 1 or bad PCM (Memory Test Failure)
(M) KAM (pin 1) was interrupted (was battery disconnected ?)

34 EVP - (R) EGR did not respond properly during test - EVP
EVR - (O, R, M) EVP sensor is/was high - EVR
PFE - (O, R, M) PFE sensor is/was out of range - PFE

67 Park/Neutral circuit fault - PNP
Transmission Manual Lever Position (MLP) sensor circuit - Transmissions
(M) Intermittent Park Neutral Position (PNP) sensor fault - PNP


This might help.

ok the 10 code means it is changing from hard codes to the memory codes but the 67 means- Park/Neutral circuit fault - PNP
Transmission Manual Lever Position (MLP) sensor circuit - Transmissions
(M) Intermittent Park Neutral Position (PNP) sensor fault - PNP

Can this be becasue the car was in first instead of nuetral during the test?

More than likely that's the problem.
