Howdy

I'm pretty sure I've posted a list of problems before, but I'm going to do it again so that I can get some opinions on where to procede.

My '98 Bonneville SE is all stock and I just rolled over 60,000 miles. I have ACDelco Platinum plugs with 8mm wires right now. I also put Goodyear Eagle RS/As on last fall.

1. BRAKES! I know this has to be a common problem. It'* happened with my friend'* '98 Grand Prix as well. The brakes are original, the rotors and drums never turned. When I step on the brakes at pretty much any speed over 25 MPH, the car and the steering wheel shake like crazy. My solution is to replace the brakes. Any opinions?

2. HARD SHIFTS. When I stand on it, it always shifts hard. If I'm driving it nicely, and the RPMS are close to 3000, it shifts quite hard from 2nd to 3rd and consequently 4th. Any opinions?

3. STARTS. Once and a while it doesn't fire right away. After I let off the key like it'* gonna start and it doesn't, it squeals like crazy. The drive belt was replaced last summer. Any opnions?

4. ROUGH IDLE. I've had the car for 4 years, and within the last 6 months it'* been getting quite a rough idle. I bought a bottle of GM Fuel System Cleaner when I was at the dealership last week, but my tank isn't low enough to put any in yet. Any other opinions?

5. LEFT TURNS. When I am at an intersection and turn left, the car will bog down. The engine runs fine, just turns really slow like I have the emergency brake on. Then, when I straighten the wheel out, the tach jumps up and everything is fine again. It doesn't do this all the time, only when I'm trying to beat a line of traffic 50 miles long. Any opinions?

I just recently had the fuel pressure regulator replaced because it was bad and I'm thinking of replacing both oxygen sensors. Anything else I should replace? I really want to keep the car as stock as possible but there are some other things I'm going to do to it like a K&N air filter and MSD coil packs. I have an extended bumper-to-bumper factory warranty good until 80,000 miles, so it'* all good as far as that goes.

Thanks!

my best advice for the shake would be to either have your rotors turned Or replaced, this just started hapening on my nissan truck and after i replaced the rotors the shake was gone. Or....get a front end alignment.
For the rough idle and hesitant start i'd do a complete tune-up.... all filters, plugs & wires etc. im no pro, but from my past experiences i have found that these simple fixes had taken care of my problems.[/i][/b]

Buy a Haynes manual from a parts store, and maybe search for and buy a shop manual on ebay. A lot of your problems are not very tough.
Like Lowlyfe said, the one about the steering wheel shaking on braking is most likely your rotors are warped. You could replace them yourself, it'* not that hard, and a lot cheaper than paying a shop.
