I am sorry your having this problem

does the check engine light ever come on ?

do you know if there are any codes set in the computer ?

Customer: replied 1 year ago.
Can't read engine light...no power to jack. Also..light is always on due to fuel tank sensor inop
Expert:  Gary replied 1 year ago.

can you check and see if the fuse # ***** in the under hood fuse box is blown it is called LTR usually that fuse is blown when the jack is dead

can you change that fuse and see if you can pull code numbers ?

Hello?
Expert:  Gary replied 1 year ago.

usually with a somewhat basic stall like this cleaning the throttle body out will correct this issue

BUT with those codes set that can be causing this issue

i would first clean the throttle body and make sure the engine oil is full then replace the MAP sensor and clear the codes and see if :

A ) the truck stops stalling

B ) no more codes are being set

Ok..I will let you know soonest
Expert:  Gary replied 1 year ago.

sure thing

we need to go at this slow as we are hoping the 14 codes does not come back if it does then we need to dig deeper into the 14 code of a bad cam actuator solenoid OR the outside chance the timing chain has play in it causing that code

Customer: replied 1 year ago.
Not as worried about the code as the symptom....if it doesn't stall in the mornings...I will be happy with that. I already bought the cam actuator sensor that was called out twice..understanding it could be caused by something else. But the cheapest way after cleaning the throttle body would be the map sensor. Car runs perfectly other than the one occurrence in the morning if I don't let it warm up....I will let you know soonest
Customer: replied 1 year ago.
Sorry.meant the cam actuator sensor is much cheaper than the map sensor
Customer: replied 1 year ago.
Idles at normal rpm even in cold weather. And if I let it warm up...never happens. The old carburetors were easier to trouble shoot!
Expert:  Gary replied 1 year ago.

thats fine let me know how it goes

Customer: replied 1 year ago.
Does that make sense? understand the risk of not clearing all faults...but that one symptom that honestly I have let go the last few seasons, is all I hope to fix
Expert:  Gary replied 1 year ago.

yes it did

i would start small and clean the throttle body and since you already have the can actuator install the new one and make sure the engine oil is full and see if it stops stalling

how are you making out ?
