Default 1995 Bonneville repair issues. Need some help, please.

Car:

'95 Pontiac Bonneville
3.8 V-6 supercharged engine
106K miles

problems:

The car shudders sometimes while driving. Does it need a throttle sensor maybe?
The car shudders during hard braking, too. Is this due to the tie rods?
CV joints, the car makes a clicking sound during take-off.

Typically, how much will the repairs cost?

Thanks in advance.

You've given us very vague information and very little to go on.

Check your vacuum lines, replace any that appear old, dry or cracked.
The CV joint in at least one axle would appear bad from your clicking description. Isolate and replace. Most likely you will find a torn CV boot with all the grease spewed on the suspension.

As for cost..it depends on who is doing the labor and where you are located for parts. In the US..a part may cost $5..in Canada that same part can cost $10-15.

Doesn't that just mean the rotors are warped? Or at least, that'* what they told me when my old SSE had the same symptom a few years ago...

Rach...it'* vague and subject to interpretation.

A shudder could be bad suspension.. could be poor idle.. when you brake hard..the vacuum booster uses more vacuum and this can make the engine stumble/stall if it already has issues/vacuum leaks.

It could be tons of stuff including the rotors...

We could use more detail, as Bill suggested. Can you describe the shudder while driving? Is it during acceleration (light, heavy, medium) or just cruising along? When was the last tune up, or any other work done to the car.

On the shudder while braking, do you feel anything strange during light or slow speed braking?

Indeed, we need more detail. For instance, is this shudder from the engine, or is it from the chassis - i.e. it is transmitted through the steering wheel? Makes a big difference in the diagnosis, exspeshully when trying to do this online.

My 95 shttered bad I thought cv also but it was #1 plug wire under acceleration would shake the engine this happened when it was still under warranty and it also had a exaust gasket bad it sounded like a cv but the mechanic changed the gasket and all better along with the plug wire.
