  1. Northstar Engines and System Technical Discussion
    Hello , I have a 1997 Cadillac Eldorado etc. V8 Northstar engine. The engine has been dying lately when I come to a stop at red lights, stops signs etc., or when I am pulling into a parking lot. Has only happened when I am coming to a stop or pulling in somewhere slowly. The electrical power...
  2. FWD DeVille 1985-2005, Fleetwood, and 60 Special
    My 97 Deville has a high idle and will shift hard into the gears - drive itself down the road when you let off the brake - harder than normal to slow the car down. I’ll explain what led up to this issue but first a couple key issues. B2750 and B2780 IPC needs to be replaced a second time since I...
  3. SRX 1st Generation Forum - 2004-2009
    I am trying to order a new radiator for my 07 SRX4 4.6l v8. Well I have 2 options. The only thing from stopping me is if mine is the trailer package or not. I don't want to waste time and money ordering the wrong one. This is my first Cadillac. I have only owed bmws. So this has me feeling dumb...
  4. FWD DeVille 1985-2005, Fleetwood, and 60 Special
    Hey all, I have a 1999 Cadillac DeVille with only 27K on the clock. Last year I took the car to the same dealership it was bought from to see if they could get my heated seat to work on the drivers side. They guy there told me the heated seat element was open and needs to be replaced. Now I've...
  5. DTS Forum - 2006-2011
    My caddy is giving me problems! I’m getting a P0449 code on my reader but the biggest issue that I’m having is that when the vehicle is in REVERSE I first have to get it to a high RPM for it to even move and when it does it only goes forward. It does stay in park on park and I’m able to...
  6. FWD DeVille 1985-2005, Fleetwood, and 60 Special
    I’m having some issues with my North Star. The temp being displayed on my dash does not match the scan tool. Even when the sensor is unplugged it shows my coolant is at 130* F when I checked it with my dmm it showed the correct resistance corresponding to the temp on my lazer thermometer. Have...
  7. Seville and Eldorado Forum
    Hello, This is my last straw here. I have fuel leaking into my manifold through the fuel inlet. I recently replaced one of the injectors and then had this problem. Finally tracked the leak down to the inlet and realized that the oring was bad. Replaced it and its still leaking. Its definitely...

    1. 2. 3. Links 1 and 2 were on the same day. I believe the weather was in the low teens that links 1 and 2. Link 3 was recorded 2 weeks before the other 2 links, normal fall weather. Temperature for the car has been fine, no steam, no overheating, coolant level looks the same from...
  9. Seville and Eldorado Forum
    60,000 miles on it, I do drive with a 45lb plate on my gas peddle so chances are it’s really bad but here’s what it does: 2 miles and it’s hot hot I can’t tell if water is moving in the system The purge line isn’t clogged but I took off from the reservoir end for 5 seconds and nothing came out...

    I know I said I wanted to do a custom exhaust on my car a while ago.. well here it is.. sounds pretty mean and doesn’t drone
  11. Northstar Engines and System Technical Discussion
    I was looking at what I would need to do if I wanted to try to supercharge my 4.6 L Northstar in a 2007 STS. I don’t really know the power capabilities and couldn’t find it out online of what these engines are rated for. I also don’t know what changes they did from the 4.4 L true STSV compared...
  12. FWD DeVille 1985-2005, Fleetwood, and 60 Special
    I got a 2000 Deville from the mother-in-law with 100,000 mi for free however she overheated it and blew the head gasket. I have been doing my homework on the northstar head bolt stripping out problem. I am going to do it myself. I don't have a lift so I'm going to pull it from the top with a...
  13. FWD DeVille 1985-2005, Fleetwood, and 60 Special
    Like the dumbass I am, I just drove home for about 30 miles on the highway doing about 70mph with the gas door open with the gas cap itself hooked on the door holder for the cap. Car ran fine, not sure how I didn’t lose fuel pressure or how the check engine light didn’t turn on but should I be...
  14. FWD DeVille 1985-2005, Fleetwood, and 60 Special
    Hey guys so I’m just over a year in owning my 96 Deville. Runs great but I’m sick of not being able to hear it. The stupid $300 mufflers that were on the car when I bought it makes it quieter than a Camry. I figured it’s time for new mufflers so I can finally hear the awesomeness of my all...

    and the 06 300 I replaced it with, one owner 157K miles $4020 all in out the door, as opposed to $425 a month for the first one. Same color even, just Limited instead of Touring. In January it will be 5 years, 22K miles, only repair alternator earlier this year and new front pads on Halloween.

    I want to replace coil packs on my Cadillac DHS 4.6 Northstar V-8. I noticed there are several different options and I know you usually get what you pay for.. does anyone know the reasoning in the wide range of prices on these coil packs, is one really that much better than the other? Even on...
