    Have you checked the vacuum line going to the throttle body? Make sure it is connected and I think the throttle body learning procedure is....turn the key to ON for 30 seconds while leaving the engine OFF to resume the normal idle.

    Give it a try and let us know.

    Thanks

    Im not trying to despute the reprograming idea.. however.. I did it with my car and it does not work. It may work on your exisiting TB but not on a new to car throttle body. Untll the throttle body is reprogramed by the dealer.. you are wasting money and time trying to figure out the problems.
    the car will never work on the new TB untill u have it dealer programed. I have been through this.. with my own car.

    Vacuum line is hooked up. yeah I know hg I have tryed that it just resets the throttle position, but doesnt program it to the ecu. I am gonna have it dropped off after I check the O2 sensors. Thanks all for your input and advice.

    That's interesting about the throttle body. I had changed the throttle body on my in-laws car couple years ago, got a used one from ebay...followed the same steps by the service manual and it worked for me.


    Keep us posted!

    Well I had it towed to a GM dealer to have them program my throttle and update the computer. I pray it works because my 96 grand marquise I bought when the Catera went down about two and a half weeks ago just died on me.

    WoW!!!!

    30 day warranty, but I want my Caddy back!!!

    Thanks for all the help will let you know

    Good news and bad news

    Good news Its back in action

    Bad news dealer said it was a bad wire harness, but couldnt tell me which one. I looked and cant see anything new. will try and find out Monday.

    Throttle Body was already programmed so

    either the key thing On for three minutes off the start worked
    or
    reseting the ECU by touching the Red and Black cables together for ten seconds reconnecting the battery wait til you hear it initialize then start the car.

    Thanks again for all your help

    Isn't there a law saying they must return the replaced parts to the owner?

    not in Florida. and since they were closing and they did me a huge favor by doing it two days early and my other car broke down had to go with what they said. I think they prob just updated the ECU and programmed the throttle just said the other so they could charge me more.

    Gota love Dealers

    I will tell u from personal experiance... I tried 2 other throttle bodies on my catera.. neither worked untill reprogramed by the dealer.

    It sounds like they reprogramed... Like I mentioned the pigtail to my throttle body was bad.. perhaps that is what they replaced. for future referance.. Always request your parts be returned to you when u take the car in... a reputable shop will automatically do this!... i found a shop that is OUTSTANDING in rochester ny!!
