Engine/Transmission (1998.5 - 2002) engine stall

[siedentopf]

I have a 2001 dodge and it will stall to idle but doesnt die, the code is a po121, it doest do it all the time but is getting worse

Sounds like the apps. It will keep getting worse. Geno`s is the best source, ask for Scott he is very sharp on our 2nd gen. trucks.
Good Luck Capt Phil
