Did you get the fuel pressure checked? What have you done, and what were the results?

Change fuel filter

Cleaned throttle body last night. No stalling today yet

Would you know how to fix rear climate control

there are actuators and boards in there you have to figure whats bad. if you do a google search on it, i found a few that had pics

Could have very well been the throttle body being dirty. Have seen this happen LOTS with these. Throw a dirty MAF into the mix and it can cause all sorts or weird problems!

What'* going on with the rear climate control?
