4.7 engine wont rev up when cold

[pauljr]

My 2004 4.7 starts immediately but when you put in drive and try to drive away it stutters and dies when trying to put it under load until the engine is warm, then runs fine, cleaned the throttle body and the three intake sensors but still the same, any ideas?

Idle air control?

Hi
It could be I haven’t tested it, I don’t know if it can be tested, I will look it up.
I’m thinking there are only three sensors between air intake and the manifold, I’m wondering if to just replace them all and see if that cures the problem.
Thank you for your reply much appreciated, unfortunately I live in the UK so nobody has the full diagnostic software, plus it needs the first generation “dongle” to work the software anyway because of the age of the truck, it has had autel and an expensive snapon diagnostic over it but nothing has been identified.
