When you go to take off it cuts out real bad at low rpm if you floor it it has all its power. Like when your driving down the freeway you have to keep the rpm atleast at 2700 then it wont cut out. Like i said though when you floor it it dont cut out and it has full power. I have replaced hundreds of dollars in parts. If you could help me i would appreciate it. Another thing when its cold it runs fine but once it warms up it does this. Thanks again

    Sounds like a bad coolant temperature sensor. At low RPM engine chokes into fuel due to rich fuel mixture.

    Thank you very much i will buy one and try it. Like I said when i take off it cuts out bad so i floor it and then it takes right off if there is anything else you think i might try if it dont work please let me know. It has been a great car it handles and has more power than our 2005 BMW 540i So i was thinking about finding a newer Diamante and trading the beemer in. Thanks again.
