Im noticing when my Max has intermitten stalling problems while im driving, the power/comfort switch tends to light on and off even when its in middle position. I switch it to the power position, does not help, if I go to comfort, still nothing. Then it stops like nothing ever happen.
I know we mention MAF, and injectors, but im wondering if it just could be this dang switch?

 

I believe the flashing being thrown at you by the power/confort switch is a code. try diagnosing your tranny see what happens.

1. Start engine and warm it up to normal engine operating temperature.
2. Turn ign switch to "OFF"
3. Set A/T mode switch to "AUTO"
4. Set O/D switch to "ON"
5. Move selector lever to "P" position
6. Turn ign switch "ON" (do not start engine)
7. Power indicator lamp should come on for about 2 seconds
Then:

1. Move selector lever to "D" while depressing brake pedal
2. Turn ign switch "OFF"
3. Set O/D switch to "OFF"
4. Turn ign switch to "ON" (do not start engine)
5. Move selector lever to "2" position
6. Set O/D switch to "ON"
7. Move selector lever to "1"
8. Set O/D switch to "OFF"
9. Depress accelerator pedal fully and release it
10. Check power indicator lamp

Codes:
There should be a longer start signal followed by 10 shorter signals, note which of the 10 short signals is longest
All flickers the same: self-diag OK
1st flicker is longer than others: revolution sensor circuit
2nd flicker is longer: vehicle speed sensor sensor circuit
3rd flicker is longer: throttle position sensor circuit
4th flicker is longer: shift solenoid valve A circuit
5th flicker is longer: shift solenoid valve B circuit
6th flicker is longer: timing solenoid valve circuit for non limited slip tranny(89-94GXE); overrun clutch solenoid valve circuit for limited slip tranny (some, maybe all auto 92-94SE)
7th flicker is longer: torque converter clutch solenoid valve circuit
8th flicker is longer: fluid temperature sensor and A/T control unit power source circuit
9th flicker is longer: engine speed signal circuit
10th flicker is longer: line pressure solenoid valve circuit
lamp does not come on: inhibitor switch, overdrive switch, and throttle position switch circuit

 

Ok 5L I tried what you said, the self diag came out ok, all the flashes were the same. Do you have any other ideas I might be able to try?
