#1377 of 2268 Oil Pressure Indication
Dec 04, 2004 (11:17 am)
Not sure which forum to ask this question. The Buick forum is not very active but the Pontiac is and I have both a Buick and Pontiac so here goes.
I just had a LOF and engine detail on my wife's 2000 Ultra. Now the DIC shows 129 psi oil pressure regardless of engine RPM. I have never seen it that high and I have never seen it rock solid unchanging. Is it possible that water from the engine detail has messed with a connection somewhere (all the other DIC indicators seem to be working okay)? Or could they have done something in the oil change to make the pressure that high?
My 04 Bonneville SLE has a gage which typically shows between 60 and 80 psi oil pressure. The gage does sweep from 0 to 120 back to 0 at startup before registering the actual pressure.
Thanks in advance for any info
#1378 of 2268 GXP Mileage
Dec 15, 2004 (11:59 am)
I had a 2000 SEii that averaged 23.8 mpg over its 96,000 miles. I now have a 2004 GXP that is averaging 18.3 mpg over the last 6,500 miles. That's a drop of some 23% with the same drag coefficients and nearly the same power rating, Is anyone else noticing this kind of mileage? The dealer says everything "checks out."

My wife has a Buick Ultra with the supercharged 3.8 and it provides an excellent compromise of performance and economy. So when I went car shopping earlier this year I was very disappointed to find that Pontiac had replaced that engine with the Northstar. I bought an SLE and am happy with it but the extra performance of the supercharger is missed. Not sure why Pontiac made the switch. The Northstar is a great engine but it displaces more and requires a deeper final drive ratio to provide performance - hence it sucks when it comes to highway economy. Hope someone from Pontiac is reading this and offers the SCd 3.8 again in the Bonnie. They offer it in the Grand Prix and have even managed to tweak a few more horsepower out of it so why not tweak it again and put it back in the Bonnie.

Insert a flat bladed tool behind the forward upper edge of the door handle bezel.
Gently pry the upper portion of the bezel away from the door trim panel.
Pull the bezel forward over the inside door handle.
Release the retainers around the outside edges of the door trim panel.
Rock the door trim panel upwards, starting at the rear, while lifting upwards to remove.
Disconnect the door trim panel wiring harness.
Remove the armrest pull cup retainers from the inside of the door trim panel.
Use needle nose pliers to compress the 360 clip.
Pull the 360 clip out of the nylon nut on the door trim panel.
Disconnect the electrical connectors.
Remove the door control module fasteners.
Remove the door control module.
Remove the push in retainers at the upper corners of the water deflector.
Push the wiring harness through the slit in the water deflector.
Carefully peel the water deflector away from the door, being careful not to damage the butyl sealing strip.
Loosen the window retainer to window clamp fasteners 4 revolutions.
Lower the window regulator about half way down.
Disconnect the electrical connector from the power window motor.
Remove the window regulator to inner door panel fasteners.
Tilt the motor end of the window regulator to the forward end of the door.
Tilt the top of the regulator toward the lower rear corner of the door.
Remove the regulator through the front access hole in the door panel.

The exact same thing happened to me. Naturally this had to happen in sub-zero weather. The medium size suction cups that you see on windows, etc. to display suncatchers, etc. Works perfect. You will need two or three. Pull window up place the suction cups at the bottom of the window. It will hold it in place.
#1383 of 2268 Soft bumpy ride 2001 Bonnie SLE
Dec 30, 2004 (8:21 am)
Has anyone had a similar problem with a bonnie. It seems to skip from side to side in the rear end when going over a bump and jumps around in the snow.
Kinda feels like it is being tossed around on a windy day, when the weather is fine.
Tire are new and the struts look good. GM cannot find anything wrong with it.
What have you done to fix the problem?

Has the alignment been reset to "right on"? My service manager had talked about slight misalignment causing hunting in the rear of cars.
People often don't realize they could drive straighter if the rear is in perfect alignment. His example was where the road is grooved out by the heavy trucks damaging the pavement. When people drive there the car wants to wander a lot more than on a flat road. Align the rear and that hunting goes away to a great degree.
#1385 of 2268 Removing 3800 valve cover
Dec 31, 2004 (12:55 pm)
I need to know how to remove the valve cover form a 93 SSE 3800 engine,particularly the one against the fire wall. Will it squeeze out after removing the 4 nuts or is there more to it. Thanks, Al

The procedure varies. What's the engine code, 8th digit of the VIN? Should be 1, 3, C or L.
