Cold sputter until warm Please Help
I am at a loss here. I have been having this cold morning start up issue. After starting it will seem to idle fine but when I tap the gas it will drop in idle for a second then jump up with gas. I have thought it just needed to warm up because it ran great after warming up. This morning I did the routine but when I tried to drive it felt like it was trying to stall out on me. I let it sit for a few minutes to warm up more and it drove better. I put a new IAC in this evening but I dont think it helped. When I let it sit at idle in park it idles a little rough. I have a whistling noise but I can narrow it down. I am at a loss here.

I kind of thought I did but I am having a hard time finding it. I did change my battery terminal connectors last night and this morning I started having these issues. I just went outside and put my old connectors back on and I did notice a considerable difference. I used the connectors that have wires already connected and you instal the factory wires to them with screw clamps. When I was removing them one of the wires just fell out. I think I had a poor connection with the battery. It was enough to crank but I guess causing some issue with running. I just put the old terminal connectors back on.

I'm having the exact same problem. I seem to have some success revving it until I pull away, and then put it in drive quick and give it gas. It surges but it doesn't fall on it's face like if I backed up like a normal person lol. I am scared it might be my torque converter

Well I seemed to have fixed the rough morning stumble and idle. Putting a new IAC and cleaning my battery terminals made a huge difference. I had a loose battery connection probably causing a number of other issues. That cold morning stumble was solved by the IAC.
