So I just got my 3.4 running good. All cylinders are firing, I'm really happy.

It's cold here in Wyoming still, like it gets below zero when the sun goes down, and about 10 degrees F during the day. (or Freedom Units like my buddy likes to call em).

Right now my 3.4 cold starts at 2000 RPMS. I thought it was crazy, so I shut it off after about a minute.

So I plugged my scanner in and it said the TPS circuit was open. I checked it and, after a continuity test, I found I had the pins mixed up on the TPS side, so I fixed that. BUT, I don't think it will help my idle, so before I start it up, I wanna know your thoughts.

I can't find the specs in the FSM, because all the troubleshooting is after the truck warms up.

This is a rebuilt motor which is why I'm being extremely careful. It's got 15w-40 rotella, so I'm not extremely worried, but still. Anybody got the specs, or your own cold start rpm to input? And do you think the TPS will fix the issue at hand?

Here's a video of the high idle

That's what mine does when "cold" (cold here being about 50 F or less). I saw someone mention in another post a while back that it's an emissions thing, to help warm the engine up to normal operating temp faster, in an attempt to keep the emissions numbers down.

Yeah I started it up again, and the rpms started at 1900 then, after 30 seconds, went up to 2500 rpm so I shut it off again. Guess it's either my make shift intake or the IAC.
