  1. 2007 CTS-V Raven - negotiating to buy in the morning - help?

    2004-2007 Cadillac CTS-V General Discussion
    The car is a 2007 w/ about 80k on it. It has failed (then passed) emissions twice in the last year of it changing hands (one dealer to another. car is 1-owner). Heard and ignored parade clunk (thanks iphone and cadillac forums on the fly!). I imagine its a result of the monster under the...
  2. Dealership is less than helpful

    2004-2007 Cadillac CTS-V General Discussion
    I have an 06 V with a few mods, cat backs, ported input manifold and throttle body, and a Lingenfelter cold air intake. Had a performance tune a couple of years ago and everything worked great for a couple of years until I cleaned and reoiled the air filter. I started getting the dreaded...
  3. '97 etc flooded after hot soak

    Northstar Engines and System Technical Discussion
    Lately, if/when I try to start my car after it's been running for awhile, but before it has had a chance to cool down completely, it will act like it's flooded - hard to start, backfires sometimes. If I open the throttle a little, that seems to help. I think one or more of the injectors must...
  4. Easy Question: Volant Intake on an 07'

    2004-2007 Cadillac CTS-V Performance Mods
    Is it possible? I don't see a Volant intake listed anywhere specifically for the 06-07 model years, which leads me to believe that the 04-05 version will not be a direct bolt-on because of the different throttle body sizes. Can anyone lend some insight on that? Also, does anyone know if there...
  5. Isc adjustment question

    Cadillac DeVille 1985 to 2005 including:1985-1992

I know that the motor...
  6. Heavier throttle spring need for ISC motor to function properly?

    Cadillac Seville / Cadillac Eldorado Forum
    Here's a strange one: On my '88 Eldorado I figured out that the ISC motor will not move in and out properly unless there is pressure on it from the throttle lever and therefore a heavier throttle spring is needed. If I do the input test for the ISC motor, the plunger should go out, out, out...
  7. 1977 cadillac throttle position switch

    Cadillac Seville / Cadillac Eldorado Forum
    Sorry if this is the wrong forum, but i'm not honestly sure where to post this. I've got a 1977 cadillac seville here (With the oldsmobile 350) and it needs it's Throttle Position Switch/Sensor replaced. I've got it unscrewed, but I can't get it off. It's hitting against a fuel rail, and I...

    Cadillac STS-V Series Forum
    Hello all, I have been looking for two weeks now for information on the throttle body for the LC3. I have come up with ONE photograph of it attached to the supercharger and not much else. I was hoping you gentleman could provide me with some information. GM Part number What other...

  10. throttle actuater control motor monitor?

    Cadillac CTS First Generation Forum - 2003 - 2007
    Hi I recently purchased a 2004 Cadillac CTS (3.6L) with 70,000 miles. It was running great, but now the check engine light is on. Sometimes when the car is started it revs to about 4,000rpm automatically before it returns to normal. Also when idling in park the engine revs up and down...

  13. 1988 Eldorado Surging throttle (codes included)

    Cadillac Seville / Cadillac Eldorado Forum
    I've recently received an 88 Eldorado as a gift from a friend. The car had been sitting for years in his shop, not having been used during that time. He said they replaced the fuel pump on the car to get it running. Neither the body nor the interior is in great shape, but I think it would be...
  14. Max throttle position?

    2009-2015 Cadillac CTS-V General Discussion
    Hey guys. Jumping over here from the STS-V forum. I have a thread over there discussing what we found http://www.cadillacforums.com/forums/cadillac-sts-v-series-forum/203798-87-max-throttle-our-cars.html#post2287466 Our max throttle position is capped at 87% max at WOT for some reason...
  15. 87% max throttle on our cars

    Cadillac STS-V Series Forum
    While recording Caoch's dyno runs I noticed at WOT his throttle position was recorded at 87% sustained max. I looked at my stock recording on my car and found my WOT runs down the street only recorded a max of 87% throttle position. WHY? I looked in HPTuners and don't see any place to...
  16. Anyone try a throttle body spacer?

    2008-2013 Cadillac CTS Performance Mods
    Anyone try one of these out yet? http://www.stillen.com/product.asp?id=EVETBS01&c=PE&year=2009&make=CADILLAC&model=CTS I'm reluctant to spend $100+ on a piece of aluminum with a circle cut out in the middle. I understand the concept, and on many cars they are beneficial, but has anyone tried...
  17. Findings dyno of 92mm intake w/90mm ported throttle STOCK LS6

    2004-2007 Cadillac CTS-V Performance Mods
    I would like to post my findings. Turkk was nice enough to do this a few years ago, but with the 90mm intake. Showing lost tq under the curve AND peak. Lost hp as well except peak. I like to find the Limits and probable outcomes. I really didnt believe the 'lose torque everywhere' average and...
  18. $10/20 min. Maint. restores throttle response.

    2009-2015 Cadillac CTS-V Performance Mods
    My car has about 12,000 miles and I have noticed it has not been as responsive to throttle input as I remembered. So I figured it was time to do a little cleaning. Picked up 2 cans of spray carb cleaner and went to work at the throttle. After removing the snorkel from the throttle and air flow...
