Just paid dealer 500.00 to replace the front engine mount. they said it took 2.5 hours. Looks pretty simple to get to under a plastic panel underneath theradiator toward the front of the engine. I suspect it takes about 45 min. there is lots of room under there. you will need to jack up the engine with out wrecking any thing though. If it fails again I'll do it my self.
Gm dealer did diagnose and repair the problem quickly. Same day service. We thought the transmission was going bad. We did have that serviced for 400.00 also. Total $900.00. And GM wonders why no one is buying their cars. They charge double for service. The car is working though. Nice car if you can afford it.

it has 4 mounts , 2 engine mounts, and 2 transmission mount
In a 2002 Pontiac Bonneville, the engine mounts are typically located at the front and rear of the engine block, as well as on the transmission. The front mount is positioned near the radiator support, while the rear mount is located near the firewall. Additionally, there may be a side mount on the driver’s side supporting the engine. These mounts secure the engine and transmission to the vehicle's frame and reduce vibrations.
i would rather not...
To replace the right rear motor mount on a Pontiac Bonneville Supercharged, start by safely lifting the vehicle and securing it on jack stands. Remove any components obstructing access to the motor mount, such as the air intake or battery. Unscrew the old mount from the engine and the subframe, then install the new mount by reversing the process. Finally, ensure all bolts are tightened to the manufacturer's specifications and reassemble any removed parts.
yes
sounds like a motor mount is broken or a transmition mount. have those checked.
http://www.energysuspension.com/forum/index.php?topic=12.0 Found this real fast. It tells you how to replace the motor mount insert, but explains how to replace the whole thing as well.
you need to remove the top engine mount
The first thing I would check for this problem would be your motor mounts. A broken motor mount could allow the engine to twist and turn causing a vibrating sensation.
you have to remove motor mount ,jack up engine use a board so as to distribute weight , loosen motor mount bolts, raise engine,remove motor mount, remove rest of bolts, remove water pump, clean area, put gasket stuff on pump,place gasket put more stuff on top of gasket ,reinstall water pump, tighten in a back and forth pattern,replace motor mount,also you will have to remove belt before anything else by moving tensioner but figured you knew that already
Yes, the 1998 Pontiac Mid-size Bonneville with the 3.8L V6 engine does have an idle control valve. The OEM part # is 17112929. Aftermarket brands will cost around $40-60. It's a small part, usually located on the throttle body. Two bolts to mount, and it's got a 4-pin electrical connector.
By taking the old one out and installing a new one...
