Second post hopefully I'll get a reply this time. Truck has new cap wires and rotor button and runs great till I'm guessing it gets warm or about 5 min and then its hard to keep running like it bogs and sputters then eventually dies and the temp gauge has not moved at all from what I've seen here on these forums it could possibly be the engine temp sensor I wowuld appreciate any help I could get

engine, model, year? these three things would probably help you get a response quicker

I'm experiencing that same issue. begining to think it's a vacum leak maybe. truck will start right back up again, and run, but not idle.

So we're clear, you have the high idle at start up and then it acts funny after it idles down once it's warmed up, correct?

Mine maybe engine coolant sensor

Have you tried burping the system? Raise the front end as high as you can get it and let the thermostat cycle a few times with the engine runing and the radiator cap off. I also would suggest pulling all of your sensors and give them a good scrubbing as they get a hard water build/scale up on them and have seen that make a difference.

So I do this with just a floor jack and what's it do get air bubbles out?

Yes. There is another way by squeezing a hose or something, but I nevr had any luck with it. This works great for me.

Copied...
Here is how I burp the cooling system. It gets alot of the air out. I raise it in the air as high as I can get it and let the thermostat cycle 3 or 4 times or about 15 minutes or so. A steep incline works well to, but my parking brake is not functioning at the moment.

I'll try it this week and post if it helps ..... you keep hose there to fill it up where bubbles get displaced and coolant level gets lower?

I fill it up and then each time it burps, I just add a little water back to it. It wont burp out so much that it is going to be to low on water. You wont get no warning of it getting ready to burp, the first time the water wont be to hot. The second or third time you need to be cautious so as not to get burned. At idle, you will probably have 5 minutes or so to add some water/coolant mix to the radiator in between burps. I use a 32 once cup or something and just poor it back in.

Doesnt really show in picture, but the radiator cap is shoulder high on me and I am 6 foot tall. It is up in the air aways.
