Last week I had my car at the dealer to fix my coolant leak. (Bad elbow connector on th eUIM) I also had them ckck to find out why it was stalling. It would not stall on them ( ofcourse) but they did find these 4 codes.

Can anyone tell me what these are? Thanks.

P0321 Ignition/Distributor Engine Speed Input Circuit Range/Performance
P0341 Camshaft Position Sensor Circuit Range/Performance
P0740 Torque Converter Clutch Circuit Malfuction
P1406 code (Manufacturer Control Auxiliary Emission Controls)
or
p1406 Exhaust Gas Recirculation (EGR) valve position sensor-range performance

OK, so cc beat me to the punch, but for future reference, you can look up many codes in Techinfo and some not found there can be found using your friend google:

It seems a little odd that all those different codes are showing up at once...

Or we could use our Techinfo source.

OBD2 is OBD2

The first two are most likely the same issue. I'd check the cam shaft sensor and ensure it'* clean and plugged in.

Oh, you mean like I said...lol...

P0321 wasn't in our Techinfo...

Yeah...once you edit your post bud... then you mention Techinfo..



All good information. Let'* help him decipher them instead of play "who got here first"

Tall, you may have multiple issues, but I would also recommend checking the connections at your PCM. It seems unusual to develop all these issues at once.

Did your CEL/SES light come on anytime prior to having these problems?

Yeah, it kicks on occassionally. It'* actually been happening more since I got the coolant leak fixed. The main result is that the car will begin to lose power, then kick back up. You can hear the heater go on and off and watch the battery guage dance.
It hasn't stalled since it'* been in the garage, but that'* what is was doing when it was stalling. There seems to be no difference in whether at low or high idle.
I know it is not the charging system since it has been tested several times.
The last time it was on a computer I was told the EGR valve and the crank sensor. I have no idea what either of those do, therefore I don't know which one is the more likely culprit.
My father in law did pull and clean the EGR valve but the problem persists.
