Default Vibrating gas pedal... and a wet trunk

That'* right, the gas pedal vibrates but only at 1500RPM. Feels like a bee buzzing under my foot. Any ideas?

As far as the trunk goes, I don't know how the water comes in. I know it pours in when the trunk is open but is it coming in when it'* closed too? I'm sure you guys have this one all figured out. Please let me know what you think. Thanks

Is the pedal loose at the base?

the way i figured mine was to:

take out everything int he trunk, carpet, spare, everything

then sit inside while i friend sprays the garden hose on it.

the leaks on mine were coming from the taillights and the power antenna

The other common leak area is at the base of the rear window. Put a thin bead of silicone sealer between the glass and rubber seal all along the bottom, and about 6" up each side.

The water can leak between the glass and seal. This is a known problem, but not too terribly common.

Short of that, the tails and antenna are good advice. Just make sure you get your spare tire well emptied of water and dry when you fix the leak.

What is the year, model and miles of your car?

My 93 has a slight "groan" to it as well. I attest it to the miles and age as I can't find anything wrong. It'* just not nice and quiet like my 99 is.

What gets me is that I can see the water drain from the tailight into the trunk when I open it. Seems like a design flaw to me.

Thanks for the ideas fellas, I'll check it out.

The car is a 97 SE - 61k.

I have the same issue with the vibrating gas pedal. I've tracked it down to the A/C....turn the A/C off and the vibration goes away....turn it back on and it comes right back. I haven't really bothered dealing with it any further, its a old car with a lot of miles....

Guess you already checked your hub bearings?

Yes. Those are new. My groan is only apparent when your foot is on the brake at a stop light, or when in park. And only when the engine is warm. I checked the water pump and it seems to be OK (simply checked for play).
