  2. Ck engine -> reduced power -> speed limited @20mph

    Cadillac SRX Second Generation Forum 2010-2016
    Anybody seen this one yet? I ask because apparently the service guy himself hasn't seen it yet - and was anxious to get it in and look at the code. So it's on the way to the dealer, but the wife experienced this morning on her way to work. I only got bits and pieces from her, but basically...
  3. Reduced Engine Power on 2003 3.2

    Cadillac CTS First Generation Forum - 2003 - 2007
    Hi, This problem appeared out of no where yesterday. I started the car and noticed that it was jerking at lower gears, so I turned into a gas station (2 mins away from my home). Turned off the car, opened up the hood, it looked clean. No leaks. Turned it on and now I had a Service Vehicle Soon...
  4. 91 Deville Hesitation and Reduced Fuel Mileage

  5. Reduced power mode with new TB

    2004-2007 Cadillac CTS-V General Discussion
    I bought a stock Throttle Body that's bored out to 78mm with a new butterfly. It was suppose to be plug and play but not so much. The car was barely idling and went into reduced power mode. Is there a way to adjust the idle, or prevent this? I put my stock one back on and the car was fine...

  8. Limp Home Mode / Reduced Engine Power message

    Cadillac Escalade, EXT and ESV Forum - 1999 - 2006
    A few time over the past years, my '03 has gone into limp home mode and displays the reduced engine power message and check engine light. I'm not sure but I may have triggered it by hitting the key to start up and pulling the gear lever into drive too quickly. It has always cleared after a few...

    I was driving my 03 CTS when the display came up something like "Reduced Engine Power" and I could only go about 3 mph.

  13. Reduced Steering Feel

    2004-2007 Cadillac CTS-V General Discussion
    Lately I have had a sense of reduced steering feel and input. The steering feels rather heavy when going around turns. I have checked tire pressures and the power steering fluid. I rotated the tires to see if the wear pattern on the front tires was the problem, but that didn't help either. I...
  14. Reduced oil consumption! Auto-Rx rules !

    Cadillac CTS First Generation Forum - 2003 - 2007
    I wanted to wait to post until I completely used a full quart of oil, but I couldn't contain myself. Another recent poster may be glad too... When I bought my 2004 3.6 auto with 55k miles, I was using a quart every 850 miles. After completing my Auto-Rx treatment, I have gone 850 miles on a...

    Ok i recently purchased a ported throttle body and installed it today, swapping out only the TPS on the stocker to the ported. The install was very easy and straight forward.
