question = HOW DO YOU REPLACE SPARK PLUGS?
JK:
You did not leave your e-mail, so i will just answer here.
First remove the plug wires at the spark plugs. Sometimes they stick, and will have to be
twisted before they are pulled off. Using the proper size spark plug socket, remove the plugs.
Check that the spark plug gap is correct on the new plugs, and install them. Put a little dab of
silicone grease in the spark plug wire boot is always a good idea. Also inspect the spark plug
wires and ignition coils for signs of corrosion. Re-assemble plug wires to the proper spark
plugs/cylinder.
The rear plugs are difficult to get to, so you will need a universal socket and extension for
those.
Be sure not to overtighten plugs or they may crack.

2004 Chevy Impala
Engine size = 3800 V6
ABS/Traction control Engine light on.
When diving in snow or rain the traction control light and ABS light comes on. Sometimes
went driving put the brakes on it won't stop it push peddle up.
JK:
This light or indicator on the dash or message center is usually related to the ABS system,
and sometimes to the check engine light. When this is on, the Traction system is disabled.
A problem in the ABS system is usually the cause but not always, and would have to be
scanned for codes. The codes that keep getting cleared are an indication as to what circuit
is faulty. Possibilities are a wheel speed sensor, wiring to a sensor, internal module
problem, etc.
