My car has 204K plus miles. I changed timing belt around 103K. Miles on car primarily highway. Do I need to change timing belt ONLY or should I buy a timing belt kit (belts, water pump, etc.)? Lastly, approx what will be labor charge?

My wife was driving her car last night when all of a sudden it died on her and there was a burning smell under the hood. When I got there, she had absolutely no power to anything in the vehicle. I took the battery out and gave it a full charge. I put it back in the car and tried to start it, nothing. Not even dashboard lights, radio, etc. I put a multimeter across the terminal and it read zero. I disconnected the positive battery cable and the mult meter read 8-10. I had a light meter? that I clipped to the positive cable and then connected to the positive stem on the battery and the light lit up. Does this mean a fuse is blown? If so, where would that fuse be? Are there other tests I can do? Is the alternator bad? Please help.

129,000 miles, ABS light comes on and pulses when ever brakes are applied no matter what the road conditions. AT highway speed the light comes on with out using the brakes. once I slow to city driving again the light goes out.

This vehicle has 250k miles but engine was replaced by Lexus at 100k. At approx. 140k car began to idle/run rough and not able to go into overdrive (OD)and bad exhaust/fuel smell. Had oxygen sensors replaced and problem went away for approx. 3 mos. but now back...had a check of codes and came back with the following --P0300, P0305, P0304 and P0446. What exactly do these codes represent and they pinpoint the real problem or just a starting point? I should also say that my check engine light is not on. Any help/guidance is appreciated.

I have owned since 25,000 miles. has 125,000 miles. Fully maintained. Just put new brakes on. Did Right Front wheel bearings at 100,000 miles. Other than that no problems. What kind of mileage do you see comparable cars lasting to? Is it time to trade in for something else?

I noticed my check engine light come on, and i also get a knocking sound when i try to accelerate.
In addition when i am accelerating, the check engine light flashes. I also noticed a burning smell, what can be the issue. it is a 1999 lexus RX300

This has occured many times in the last few weeks, i have been told that it is some type of control valve that needs replacement.

Where is the tail light relay located? Could this be my problem?
