Bri, not sure if you still have that problem, or the car for that matter, but the problem you experienced sounds a lot like the one I had a few years ago. It turned out to be a faulty connector wire to the fuel pump, the one that comes down from the fuel pump and connects to the wiring harness ...

I am assuming that to remove the driver air bag unit (this one already deployed) there are bolts tucked into the holes in the back half of the steering wheel. I can't see what kind they are, even with a mirror.

Can anyone confirm what type of screwdriver I need? Since I couldn't find one with a few ...

My downpipe has developed a rattle most noticeable on start-ups and remains loud until the engine has fully warmed up. Annoying. My cousin who is a muffler shop owner explained to me that the rattle is the inner sleeve of the stock down pipe that has rusted loose.
I bought a new 3" stainless steel ...

My hard shifts never came back after installing a 180 thermostat and a tuned pcm that runs your radiator fans properly. That was several years ago. No more heat soaking, no more shift banging.

BTW, if you pull over and turn off the car for a moment the hard shifts should go away until you get home ...

Old yes, but it is the only post on this entire forum that solves an irritating loud clunk and rattle every time your rear end goes over the slightest bump or pot hole. Everyone here immediately (as I did) fixates on shocks and shock mounts as the culprit. Lots of money has been spent tryng to nail ...

Great to see that you are still helping so many 00Beast. A special cheers goes out to you for your valuable assistance.

is the front one more likely needing replacement?
Or definitely do both? Seems a less expensive route than having the shop test the existing ones..lol

I'm going to put my car back on the road after a 12 month sit w/o a battery in the driveway. I'm getting a number of regular things done before cranking her over plus a few upgrades:

Regular stuff
oil change,
new K&N 9" cone filter (trust me its due)
tranny oil change? -- (and filter ? -- had ...

After almost a year off and on of trying to find a rattle at low speed going over bumps I finally found the problem. I replaced the shocks, new shock mounts, and even replaced the left torsion bar to no avail. Finaly I discoverd that one of the body mounts under the rear door had somehow rusted ...

I replaced the shocks and mounts twice. Nope, it was lose body mount bolts. A 30 cent thicker washer placed on them eliminated the clunk for good. I cringed about that clunk for two years. Search for body mount bolt or click on this link

1. If you are a recently new member (last 2 years), do you find it helpful that our Gearheads are clearly identified by RANK? Does that make a difference when you read their replies?
YES

2. If you are a more veteran member, do you think the Gearhead rank is being properly used here?
YES

3. If you ...

I'm about to order the 3" DP from ZZP and wondered whether I should go with the aluminized or with the stainless steel for the extra $50 bucks. Is there really any difference in terms of longevity, looks, installation or performance?

Second, how many extra horsepower am I missing out on by not ...

So I have replaced everything as stated in the common issues sticky for this problem (replaced plugs,wires,coils, and ICM) and it's still there. Any suggestions what this could be would be great.

I know this may sound odd, but check your front motor mount for tears. I think your getting engine ...

FWIW my front struts are weak enough from so much mileage that any unusual combination of manouvers will set off the service stability warning - like ramping off the end of my driving and turning at the same time. I think a good wind gust from the side once set it off - lol.

FWIW, for a while my cruise control would disengage whe I used the left turn signal. Problem eventually went away.

okay i get the idea of the front mount out of hockey pucks. is it harsh or with vibration because of the solidness?

This is the easiet mod I did to my car and love it. I initially felt some vibration in the gas peddle, not really too bad that I wouldn't have got used to it, especially since it ...

If you smell antifreeze then it's your heater core.

Personally, I would start examining the door panel water reflector sheilds that comonly come unglued. They are common causes of water in the carpets. I reglued all my sheilds - they all ended up failing at certain points. Check front then back ...

Don't forget that the door panel water reflector sheilds that come unglued can also be the cause of water in the carpets. I reglued all my sheilds - they all ended up failing at certain points. Check both front then back sheilds.

Yeah, the Sunroof drain tube on the passenger side isn't too easy to ...

2003BlackSaphire,

try this where you won't get a speeding ticket...

if you go into Neutral at say 75 mph and coast down through the shimmey zone speeds the shimmey will occur (drivetrain disengaged).

If this occurs for you too then this eliminates motor mounts as the drive train is not engage ...

If you have or have had the front end shimmy, has anyone just simply replaced the wheels with aftermarket wheels, with new tires with a good balancing job and front end alignment, and that resulted in absolutely no improvement in the shimmy?

Yep I have, my brand new after-market wheels and tires ...
