hi
I'm new here
in my 2004 F150 automatic was replaced last week all the parts related to time, the whole kit, chain, guides and everything.
now is still presenting some problems, it stalls when you reach a light for example, no engine light and no codes in computer,
what can it be?

 

Pull the connectors to the VCT sensors and try it again. You'll get codes now, but if it doesn't stall, there's your problem. Might also be a plugged cat, but the VCT test is an easy one.
