Truck idles rough. Runs a little better after warmed up. When the AC is on. The engine will turn off when you are stopped/clutch pushed in. As long as you are moving the AC can be on. This has happened before. But the symptoms go away after a day or two. It has been seven days with this problem.

Has the check engine light come on? Have you checked for vacuum leaks?

Let me know.

I would suggest checking for vacuum leaks. Also, I would suggest checking fuel pump pressure when it's cold. If you need instructions, let me know.

Here is a how to video and directions for checking fuel pressure. You will need a gauge, but most parts stores will lend or rent them to you.

Here are the directions for checking for vacuum leaks. Again, you will need a gauge. Check the parts stores to see which will lend or rent it to you.

Let me know if you have other questions.
