The bogging when the heat comes on is something I'm going to have to think about.... The first thing that comes to mind is that the heater is drawing more current than the alternator can provide... could also account for stalling. Check the voltage from the alternator and then while watching the meter have someone turn on the heat.

As for the stalling I'd start with checking that the ISCV (Idle Speed Control Valve) isn't clogged and test it; Then test the AFM; Test and calibrate the TPS; Check for vacuum leaks or openings in the intake piping.

ok im sorry this took so long but i just got the codes.
22 Engine Coolant Temperature Sensor signal.
24 Intake Air Temperature Sensor signal.
41 Throttle Position Sensor signal.

if i am right 22 is that makes the car hard to start if not plugged in and its not doing that and it is plugged in

24 i have no clue where that is

41 is also plugged in and working

are these stored codes or what? also im going to try the tps calibrating
