2000 Camry Idle & Noise problem

my 2000 Toyota Camry LE
Auto Transmission 4 Cylinder
160,129 miles on it
i got it from the dealer bout 6 months ago

my power steering fluid was leaking so i put in Lucas Power Steering Stop-A-Leak

i was quart low on oil, i always get my oil changes on time, its due for one in 2000 miles

i got the Lucas Oil Stabilizer

1000 miles ago when i got my oil changed i used Seafoam =)
n well

When i turn the wheel all the way in any direction the car gets a tad bit louder and it starts idling heavier like you can watch the RPM's go up a lil bit n if you hold it their the RPMs stay up a lil bit

i remember when i first got this car about 8,000 miles ago it didnt even make a sound when it was running

so my question is why does my car idle more when i cut the wheel all the way?

Why would the motor get louder?
just wondering! Thanks!

Also when i push the pedal sometimes it feels like somethins between the pedal and the floor stopping me from giving it gas... then when i give it enough pressure to go down it goes too far like im mashing it!
notta big problem here... i just learned to like try n click my foot like hit it harder with my foot then i normally would n let off n then give it gas
or its kinda reminds me of kick starting a dirt bike lol you know what i mean?

Plz help me =)
P.S Nice forums =D

When you wheel is turned all the way to either side, the power steering pump is working it's hardest to produce the required pressure. The computer in the car senses this and raises the idle slightly to compensate for the load on the engine. This is probably what you are hearing. Two things you can check here to may sure your car is running normally. First, I would suggest you keep your oil level topped off at or near the full mark. If the level is down 1/2 quart or more, add just enough oil to bring it to the full mark. Second, I would have your exhaust system checked for leaks. You may have a small exhaust leak which is most noticable at idle when the idle is raised slightly.

As far as your pedal problem, it sounds like you need to clean your throttle body. The throttle valve (essentially a butterfly valve) is probably sticking inside the throttle body. This is common as these cars get some miles on them and dirt and other deposites build up inside your throttle body. Do a search for "throttle body cleaning". This is something you can do yourself.
