First of all thank you so much for your donation.I need a little more detail from you. So it run's good cold in park?What if it's cold and you put it in park does it still run good?Do you have any code's?Also ever have any trouble starting it when it's hot or cold?Also when it dies when it's hot does it restart right away or do you have to wait a little while before it will start?The more detail's you give me the better the chance of me helping you figure it out.

It run fine when cold, idles at1000rpm in park, when shift into gear stalls, and stalls when accelerator is pressed. If you make make pass the stall it run ok, but at steady speed heistate intermittent. And completely stalls when stoping if you did not keep foot on accelerator.

The coolant temp sensor's on those car's go bad a lot and cause all kind's of problem's.I suspect yours could be bad as well.There only 10 if you replace it make sure you get a brass tipped one the plastic tipped one's crack.If you want to test it first i posted the ohm's value chart for it you would take a ohm's meter when it was cold and you knew what the outside temp was then see what the ohm's value was compared to the chart and see if it was reading the correct temp.Also check the connector going to it if it's corroded they usually turn green then you would have to replace the connector also.To unplug the connector you have to squeeze the connector.But i will leave if you want to check it or just replace it up to you.I would like if you check it first so you don't replace it for no reason but that's up to you.Let me know what you find.
