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.
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.
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 [non-permissible content removed] 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.
First time posting on the site. I'm 30 and recently purchase a 2001 Deville DTS with 79,000 miles. Very happy with the car but a ER.2 message appears on the dash before i start the car and leaves after it starts. What does this message means. I'm still under warranty and want to fix any problems as soon as i can. If anyone can help thanks.
This is a complicated discription of my problem, so I'll jump right into it. As you read this, keep in mind that my back-up lights NEVER work.
My brake lights work properly when the headlights are off. All three of them come on, and no bulbs are out.
With the headlights on:
When I turn my headlights on, the third brakelight (above the license plate) does not work. The license plate lights are extremely dim, not really illuminating the license plate at all. The light-up pattern of the taillights is different also. The entire taillight is lit, except for the lower inside quarter of each taillight (not applying the brakes). When braking, they light up properly, and they blink properly with the blinker on. If I disconnect the third brakelight, the normal taillight pattern comes back (a thin stripe on the outside edge of each taillight), but all other problems remain.
The trunk courtesy light is always dim. When it is removed, the license plate lights go off. The license plate lights also go off when the trunk release is disconnected.
It seems to me like the trunk is not getting the proper voltage to carry all the lights.
POSSIBLE SOLUTIONS:
1. Replace the wiring harness in the trunk (Grounded by the left taillight)
2. Replace the headlight switch
3. Replace the dim bulbs and see what happens.
Also, could the traction control be carried on the same wiring through the trunk? Because when this started, the yellow traction control light comes on in the instrument panel periodically. I can't pinpoint what is triggering it though. When that light is on, I cannot manually disengage the traction control with the button on the center console. This could be a separate problem though.
Can anyone help me, or direct me to someone who can? The car can't pass inspection without the third brakelight and backup lights.
I'm at a loss as to what could be wrong. Have you received any good directions what to do with your problem? I won't drive until I am sure the problem is fixed.
I´m new here so sorry if I´m posting in wrong forum.
I own a Seville 1991 V8. There are two fuses under the hood named INJ (Probably Injection?) of 7,5 A each. One of them are very often popping which makes the engine only perform 50% of it´s capacity according to my experience.
Any ideas of where to start analysing the problem?
Kind Regards Himzo
Any help would be appreciated.
If this problem continues, I would guess the problem being the battery cables, the positive or negative. Corrision has probly gotten inside the rubber and eaten almost thru one or both. A common problem on Cadillacs.
The positive cable is somewhat complicated and expensive to replace completely. It will go from the battery to the starter, which on a Northstar is inside the intake manifold. Intake must be loosened and lifted to get to the end of the positive cable.
Has someone put an after market radio on the car?
Has someone put an after market alarm system on the car?
Has someone put a remote start system on the car?
Any of these has a high possibility of messing up the electronics on a Cadillac, or any other vehicle.
They replaced, per receipt, a relay, a module, etc in the attempts. I think the final fix was a short or bad connector, not a separate piece of hardware.
I didn't ask much about it, just kept taking it back. And on the last trip home, after 30 minutes on my driveway, I saw green fluid. Took it right back and got a replacement water pump in less than 2 hours. Had it in stock, knew what the problem was, quick replacement - this makes me think lots of them leak.
And, you have to disconnect the battery to stop the interior lights, until they are fixed.
Yes, the northstar water pumps do fail every now and then. Most water pumps fail before the engine does.
Got to Auto Zone trunk wouldnt open with key
The new solenoid and camera and tools all in trunk They were to busy inside to help Also wanted to ask them to let me know codes for "service engine soon"
What do I do go to locksmith or body shop??? I hope wires not caught in lock I doubt cause old solenoid was still attached with last white round plastic plug cable that I couldnt "unplug" or release
Thanks

I have two annoying problems that I can't figure out:
1. How do I reset the information display to show 100% Oil Life after I've changed the Oil???
2. I have a button in the passengers glove compartment marked "Valet"I guess this is a security measure to prevent the Valet from opening the trunk. How does it work???
I have intermittent success when trying to open the trunk with the remote. Sometimes it opens the trunk & sometimes it doesn't. The button in the dash displays the same symptoms.
I'm totaly confused by this!!!
Any help would be appreciated.

2)Push the valet button. Lock the glove box. The trunk cannot be opened with the key.
Owner's manuals can be bought very reasonably on eBay. www.helminc.com will sell you a new one. With all the 'stuff' on a Cadillac, you need one, and you need to read it. Lots of good stuff in there.
There are no replacable bulbs.
The controls themselves have to be replaced.
Bought my 04 Deville about 6 mos ago w/25K miles. Have about 30K miles now. Very pleased with the car, but I'll try to be as objective as I can.
1) Replaced the Air Pump (caused check engine light)
2) R&R front rotors and new pads (normal wear/tear item)
After correcting the above items I've been very pleased.
I do have a minor annoying windnoise issue I still need to address though. This is all covered under warranty.
Even after considering the above issues, I feel my experience has been very good so far. I really love the ride and performance of this car. I truely look forward to driving it every day.
I really haven't owned my Deville that long, but so far no regrets. Hope this helps with your decision.

I know it has something to do with the suspension or steering, but is it serious?
Can I reset or should I take it to the dealer and get bent over? How do I reset the light?
Thanks
