Feels like it lost power. Any common problems?

Im going to start by changing the plugs.

Probably just in your head. I think when people get used to the power of a car that they can eventually convince themselves it has lost power. It's all relative.

No its not my car. Its my neighbor's. He ask me to take a look at it. It does feel slow to me. My brother's 98 gs400 feels faster then the LS430 i drove.

No CEL.

Im going to change the plugs. They aren't that expensive anyways.

I think my 92 sc400 even has a chance.

the air filter was a little dirty but he said it was replaced not too long ago. i cleaned it out for him and change the plugs. not sure if its to normal specs but does feel better then before.


NOW im trying to fix the door handle unlock button. im not sure what it is called since i dont have a baller car. lol he said before sometimes it would work but now it doesnt work at all. he replaced the battery on the key, but still nothing.

Does it have to be reprogrammed? or
is there a fuse for it? i looked in the fuse panelss and didnt see anything,

thanks

First thing I would do is clean my fuel system. Run a bottle of techron through. And maybe on the tank after that, a dose of lucas upper cylinder lubricant/injector cleaner.

Air filter should be checked or replaced.

If those things don't fix it, you could always do a full tune up including spark plugs.

The button on the door handle is to lock the door (if you have the smart access key in your pocket). You grab the inside of the door handle to unlock the door. The smart access power button under the dash, above the driver's knee, must not be off.
