recently purchased a 99 es 300 coach edition with nakamichi audio from a dealer. silky smooth engine. i observed the following issues and hope some forum member could point me to correct links or DIY info.
1. nakamichi audio is awesome. however when i bump up the volume i hear a jarring noise. i suspect the woofer is going bad. do i need to replace the entire woofer or any quick fix. if i have to replace is there any online reputed location.
2. how do i know whether the previous owner used synthetic or regular oil. i prefer to use regular oil.
3. occasionally i am unable to depress the accelerator when i am at stop signal. it seems stuck and i have to press hard to unstuck or release. is this a common issue.
4. it came with only 1 key (black) which i can use for all -trunk, ignition, glove and door.
Does the original remote comes with key or remote only. i would like to fill the void. i saw on ebay for remote with uncut key. I am planning to get one for spare and where do you get the key cut. i saw programming instructions on this site. if i try to program the aftermarket (ebay) key and remote will it mess up my original master key. what are the functions on the original remote.
5. the steering wheel has some chips due to heat. is it easy to replace the steering wheel.
any assistance is appreciated.
