Car dies out at idle. Don't know the location of the sensor. I also hear a click when I step on the brake pedal coming from the shift location or emergency brake.

There are no misfire or noticeable effects.

The 02 sensors available have a shorter wire and the old wire is about 2ft long. The available sensor now is about 6inches.

1999 Lexus SC400 only 59k miles but 14 years old. sounds fine just replaced 5 ignition coils and no current codes or problems. New plugs, drive belt, oil and air filters.

When I purchased the car it had 3 aftermarket cheap ign coils and I installed three good used oem coils. Still cutting out but better.

Car has been sitting for eight months. 59k miles new plugs installed year ago. Runs fine at high speeds with no hesitation.

Two problems: 1)Noticable vibration at 2000 rpm in Park. Noise heard about 65-70 mph like a harmonic sound (clothes washer sound). Tires have been replaced. 90K service performed in November including all belts, timing belt.

Hello: Was wondering how much would it cost to get a new master key w/ attached remote control?? And how long would it take??
