Repair Questions and Answers
Question: 1996 Toyota Avalon V6
mileage: 104,500. The engine light in my car went on and
the car began shaking. I brought it to a mechanic who
found a dead spark plug. He replaced the spark plug and
everything seemed fine. One week later the engine light
went on with the same symptoms. Any ideas what may be
causing the spark plug to burn out? Any ideas as to what
may be wrong?
Answer: Check the spark plug wires
as they may be breaking down. Also, check the "dead"
plug to see if it is oil fouled due to leaky valve stem
seals or possibly piston rings.
Question:
1998 Toyota Avalon V6 mileage: 115,000. When
accelerating, a cluttering noise can be heard from
engine, especially if accelerating up a hill. Have
tried different types of gasoline. Nothing helps.
Any suggestions as to what it could be and what I can do
about it? Thanks in advance.
Answer: Your engine is equipped with a
knock sensor, which adjusts the ignition timing to the
computer. Yours may not be functioning properly.
Question:
1998 Toyota Avalon v6 mileage: 120,000. Without
warning, the air conditioner & fans quit working.
This car has an outside air temp display & it suddenly
does not show a temperature reading. I checked
every fuse I could fine with a meter. All ok.
The car starts & runs fine & all other electrical works
ok, i.e., lights, rear defroster, windows, door locks,
seats. It is equipped with an auto mode for the
air with a temperature adjustment that will control the
blower speeds. This is not working, or if you try
to punch manual blower speeds, (each button will light
up) but will not turn fan on, or if you push the ac
button, will not work or light up. No engine
service light either? Thanks!
Answer:
Check wiring for damage or loose connections. Check
ground connections.
