Just recently when I start my truck when it's cold (starts up fine and idles fine) and put it in drive and give it gas it starts to studder like it wants to die. Does anyone know what can cause this? Once it starts going and also when it warms up it is fine. It just does this on the initial movement. Does the engine run off a different air/fuel table when it's cold and maybe the computer has a bug somewhere? It has a new fuel filter and good plugs and wires.

 

I have had this problem also a few times but don't know what it is all help is appreciated

 

Check for buildup inside the throttlebody,it may need cleaning.

 

I have that problem too ive never had it die on me though, i just think its just cold natured, i also have 80,000 miles on stock fuel filter plugs and wires so thats not the problem.

 

For cold starts, the engine runs in open loop until the coolant temperature rises above a certain point (something like 140*F). In open loop, cold engine, cold intake air - the PCM adds extra fuel when you put any load on the engine. Try letting it warm up a little longer before you begin to drive...

 

Mine does it too, Kyle. I always let her warm up a little. I also noticed one day when it was below zero, that it sounded like it missed a few times right when it started. I don't think the injectors liked the cold or something. Your cold stumble is pretty common though. There may be a PCM update, but don't have them do it since you have programming in yours.

 

Does anyone have any additional insights into this problem?

 

I'd try cleaning the throttle body as a starting point...

 

we had this problem at work on our 2000...the stealership replaced the MAF and the problem disappeared...
