  1. Ok thanks. I found the sensor on line for 26 dollars I will order and let you know how things go. as for vacume test I did a leak test and found no leaks so I think this broken sensor will do it but I will let ya know. Thanks for all the help guys.
  2. I just checked and found a sensor broken under the spark plug wire cross over plastic bracket / chanel. I thick it is the temp sensor but not sure. It is just to the left and on the front of the intake manifold. It is a green 2 wire plug and the wires are red with blue stripe and a brown wire. Yes the car runs just fine after it warms up. As for back ground we had the intake manifold gaskets change and shortly after this problem started. I was out of the country so I did not over see the work done. Guess if you want things done rite you got to do it your self. So if this is the coolant temp sensor why does the dash gauage show temp to run ok? I will order the sensor and post the results here. Let me know if this is a temp sensor or what you think it may be. Thanks so much for your help.
  3. I will check on the cap now. I asume by all the post I have read that there should be presure in the tank at all times? Also I will see if I can find how to add more details to my profile. Being new to this site I am not sure I am doing this rite so thanks for your reply.
  4. Hello all. First of all I am a new member and want to thank all of you for your post they have been most helpful. Now I could use some help with my LS 400. It will not start in the mornings unless you crank on the starter for a long time or in cold weather you actually have to shoot starter fluid into the intake and she starts right up. Once it starts for the first time she will start all day but left over night you get the hard start issue again. I am a High Horse Power Diesel Engine Tech for Komatsu America. When I see this issue in Diesel engines it is usually the fuel pump or the fuel system is sucking air or there is an inlet fuel restriction but they will have power complaints. Anyway my Lexus will run fine after you let her warm up. I did notice that when it first starts in the morning if you hit the throttle right away it will stall like it is running out of gas but let it run 2-3 min and it responds just fine. She has 194k miles and the wife loves the car I just need to get her up to par! The car that is not the wife LOL :chairshot: Any help with this will be greatly appreciated. Thanks.
