Throttle Body Inspection and Cleaning (1.6L LDE, LXV, 1.8L 2H0,
LFH and LUW)
Note: Over extended time
and mileage, deposits may accumulate on the back of the throttle
valve plate. The source of the deposit is exhaust gas. Typically
these deposits pose no problem. Occasionally the deposit may
accumulate to a point where perceived pedal effort or throttle
valve movement is effected. This procedure should not be performed
on vehicles with mileage under 80,450 km (50,000 mi).

Warning:
Turn OFF the ignition before inserting fingers
into the throttle bore. Unexpected movement of the throttle blade
could cause personal injury. |
|
Caution: Do
not insert any tools into the throttle body bore in order to avoid
damage to the throttle valve plate. |
2. |
Inspect the throttle body bore
and the throttle valve plate for deposits. You will need to open
the throttle valve in order to inspect all surfaces. |
|
Caution: Do
not use any solvent that contains Methyl Ethyl Ketone (MEK). This
solvent may damage fuel system components. |
3. |
Clean the throttle body bore
and the throttle valve plate using a clean shop towel with an
appropriate cleaner. |
