#53 of 151 Re: Still looking for information to "Upgrade" from horn to chirp. [bremertong] by 04cad Aug 25, 2006 (12:55 pm)
Replying to: bremertong (Aug 16, 2006 7:25 pm) Thanks for the helpful advice. When I get a moment I will definitely talk to the dealership. After the last service visit when they got greasy footprints on the driver's floor mat we will be going back to speak to the manager anyway. They usually put paper mats down, but for some reason this time they didn't... bad move. If GM really wants the title "World Class" I think they are going to have to straighten out some of their dealerships. I hate complaining about them all the time, but it is pretty obvious the dealerships must have too many customers the way they treat the ones they have.

I actually do my oil changes on my 2004 Deville at the Chrysler dealership which I have found to provide better service than either Ford or GM. The companion car to my Deville is a 2005 Lincoln T. C., bought recently but expect to try Chrysler dealership for oil changes for it too. My question would be are the Japanese builders exercising more oversight over their dealerships and is that one of the reasons that Toyota and Honda are getting higher ratings than than Ford & GM? I have never owned a Japanese car but am somewhat frustrated with the attitude and service received at the big two.
#55 of 151 2002 DHS by josh20 Sep 01, 2006 (10:11 pm)
Have 2002 purchased in 2004; wheel sensors left front had to be replaced; now right front sensor needs replacing. Now have check stability light with ABS Brake and other lights that won't go out. Dealer checked today-will cost $2000 to repair. Trying to keep this short. We are frustrated--Has anyone experienced this problem?

Replying to: josh20 (Sep 01, 2006 10:11 pm) I didn't see where you said how many miles this car has on it? Have they checked the front bearings? My daughter's car had a sensor problem, the dealership said it wouldn't be dangerous to drive it that way, later on the bearings turned out to be going bad. The sensors and ABS are all close to the bearing area on some, maybe all, GM vehicles. This could be the start to a bearing problem if the car is around 100,000 miles.

Replying to: josh20 (Oct 05, 2006 9:22 pm) I believe all of the late model GM products have a second generation air bag that is safer for smaller occupants compared to the first generation air bags that were reported to have dire consequences for smaller occupants. Their trucks once had a switch so you could turn the air bags off when necessary, the late models do not have this switch.
#60 of 151 runaway idle speed by sickcaddy Jan 28, 2007 (6:48 pm)
2002 standard NorthStar engine - 225K miles - when car is moving on a level concrete road, it will accelerate andhold a speed of about 60MPH with no curise control and no pressure on the accelerator. Putting tranny in Neutral while vehicle is in motion results in idle speed of between 2,400 and 2,600 RPM until car runs out of gas (for you guys who want to know How Long?) or until the vehicle comes to a complete stop. Within 3 seconds after complete stop, the idle speed takes about 5 seconds to gradually reduce to 1,400 to 1,600 RPM. Have changed all sensors called for in error codes. Cleaned throttle body.   Cold start idle is normal until engine reaches normal operating temperature, then it speeds up.   I am not a mechanic, but I sincerely believe this is not caused by some sticky accelerator or other strictly operator controlled mechanical reason. It is in the computers somewhere - of course, I already told you I ain't no mechanic - or service tech either. THANKS fo your help. Replies to this message: bolivar (Feb 12, 2007 8:44 pm)
#61 of 151 replacing license plate bulbs by dhs1 Feb 12, 2007 (2:17 pm)
Anyone know the trick to replacing the bulbs that illuminate the license plate on a 2001 Deville DHS? You can't access the bulb from inside the trunk so there must be a way to just remove the plastic transparent cover on the outside, but I don't want to break it in the process.

Replying to: sickcaddy (Jan 28, 2007 6:48 pm) First thing to always check - for a floormat that is hanging on the acc pedal, although this doesn't sound like it. Floormat would not return to lower speed in nuetral.   Next, did you said you cleaned the throttle body. Did you clean just the tube, or did you also clean the throttle butterfly valve. And clean it good, both the front and back of the valve. Was there a ridge of gook where the valve closes on the intake? You must scrub the gunk off with a toothbrush and carb cleaner, front and back. The back will be much worse. The gunk will cause a Northstar to actually have the throttle hang.   Mechanical binding of the throttle cable?   On the 1997 Northstar I messed with, there is an Idle Control Valve on the intake. There is a (what's it called, the thing that feeds exhaust gas back into the intake??) The idle control and EGR (that's the name, exhaust gas recirculation) valves are right there on the intake, by the throttle valve, and these can be taken off and the passages checked and cleaned. An Idle Control Valve usually has an electrical solonid on it, do not get carb cleaner into the electrical part. But clean passages. There is also a Mass Air Sensor on the intake. I've never taken a Northstar appart, only a Ford Ranger. It has very fine wires inside that can be cleaned by spray electrical cleaner, I think carb cleaner is too strong for these. Be very careful with Mass Air, the wire is very fine. Do not touch.   All these effect idle and at high milage can be gunked, dirty , etc.   Anyway, something else to check.   You have high milage on this car.
