Are there any codes in the computer?

Do you have access to a scanner that can read live data?

No codes

 

No access to scanner unless I take it to Auto zone

Ok.. You could have a bad IAC motor, THis is very common!

Also, sounds silly, but if the transmission fluid level is low, then this can cause your stalling too. Be sure the transmission fluid level is correct, low fluid level can cause torque converter clutch release problems. There is a TSB about this problem. It is TSB# XXXXX Verify the fluid level is normal, a low fluid level on this transmission can cause the torque converter clutch to disengage slowly. This transmission is very fussy with the fluid level and the level on the dipstick can vary greatly with transmission fluid temperature. Make sure the fluid level is Ok according to the transmission fluid temperature, see service information for the details.

Also, If you can get access to a scanner, Check the Clutch Volume Index (CVI) on all the clutch packs. On this transmission the normal values are as follows: L/R=45 to 134, 2C=25 to 85, O/D=30 to 100, 4C 30 to 85, U/D=30 to 100.

If all of that stuff checks out ok, you might just have a bad camshaft or crankshaft position sensor. These two are very common!

I was under the iimpression that my hemi 5.7 does not have a IAC. Idle air control? If so I can't find it.
Expert:  Amedee replied 5 years ago.
If it has one, it is located on the throttle body. If not, it is throttle by wire.
Customer: replied 5 years ago.

I will check fluid tomorrow when engine is cold then I will check hot.

There is a cover on the side of throttle body but is not acessible. Inside the plastic air intake housing between the air filter and throttle body is that a heat sensor or is that the IAC?

Expert:  Amedee replied 5 years ago.

If it looks like this, then you have throttle by wire.

This exactly what it looks like. So there is no IAC. When scanner was hooked up to electronics under dash there were no codes. I will see where I can get access to a scanner to check CVI. Is this scanner only available at dealer?
Expert:  Amedee replied 5 years ago.
YES.. there are a lot of scanner. You can get them all over the place. Your local auto parts store might have access to a scanner that can read live data.
