I'm back again with same problem. Finally got the crankshaft sensor put on the one close to crankshaft. Same problem when it reaches normal temperature it will stall. When I make turn, but starts right back up again. Can it be ignition coil?

Are you saying it stalls when you turn? Or does it stall once it heats up only?

This sounds like you have a engine coolant temperature sensor that is going out, when it get hot is shorts or you have a wiring harness that is grounding out. With the car running grab the engine wiring harnesses and move them all around see if you can get it to stall. If not here is a guide to help walk you through the steps of changing the sensor and the location of the sensor below:

Check out the diagrams (below). Please let us know what happens.

I'll try that with wiring. But today I went over a speed bump, I was going slow, bump is in parking lot of apartment complex and it stalled. Something must be loose. I think.

Yep, grab the engine harnesses and move them around to see if you can get it to stall.

These can be a bear to find, wiggle test works but don't just grab the entire harness, move only one piece at a time. Because it is doing it over bumps a trick is to use something like a piece of wood or similar (no metal) and gently push down on the harness, especially in areas where there are sharp edges and brackets.

That looks like the PCV line. If the other end goes into the valve cover then that is it. The end near the throttle body goes into a hole on the boot from the airbox to the throttle body.

I found what makes it stall. While engine running I shook that tube and it stalled.
Now the PCV valve tube is taped to that red tube both are hanging loose on the other end of from where they come from the engine. Do they belong somewhere?

Could you take a picture and load it here, the PCV tube shouldn't make it stall, if anything it should gain RPM from the vacuum leak. If moving another hose does cause it to stall I would look really close to see if it's cracked or damaged. A picture would help as there are a few other items there as well.

I didn't get any gain in RPM from leak. In the picture where you see red circle was bad.
Replaced PCV hose. No longer stalls. Runs good Got it up to normal temp(195) made U-turn no stall went over speed bump. No stall.I don't know what to tell you but putting
new PCV hose on did the trick. Thanks for all your Help.

The end with the elbow goes to the port on top of the valve cover (2). The T fitting goes into the top of the throttle body, the straight end of that line goes back to the lower fitting on the valve on the other valve cover.
