Gas pedal will not excellrate.

only when car is cold ( first starting out my day) Then it's fine!

Any suggestions?

It will turn over but won't start

I heard some sound from my engine this morning immediately I start the engine.

I can't get the cover off

The battery seems to be OK. Is there an auto shut down feature, anti theft or other system that is doing this? I bought it in April 2014 so this is new to me. Any advice?

It sometimes says that I am over the speed limit when I am actually driving at the posted speed limit. Very irritating

all of a sudden the light came on.

I WOULD LIKE TO REPLACE MY RUBBER TIMING CHAIN WITH A METAL TIMING CHAIN IN MY 2001 LEXUS LS430. CAN I DO IT???

every time I go down a uneven road the front end makes a bumping noise like something is lose, no one seems to find it.

My Lexus LS 430 2001 has 120,000 miles on it and per the manual I think its time for a spark plug change- what is the best spark plug- Denso or NGK?

The speaker appears to be split and therefore makes a terrible noise when more than a little volume is turned on.

I added water to the battery before discovering in the manual that you are not supposed to add water to the battery. Will this damage it? A light had been left on in the car which drained the battery originally, but charged it up, saw water was low in battery , so added it. What happens if there is too much water in the battery?
