Problem with my 2005 impala 3.4L.
Question = HOW DO YOU REPLACE SPARK PLUGS?

Answer:
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 over tighten plugs or they may crack.

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.
Answer:
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.

Repairs for this problem = replaced cracked intake manifold fouled spark plugs and plugged
catalytic converter. Car came in with P0174. Customer complained very hard to start burning lots
of fuel. Attempted to reset fuel trim after repair;car still runs extremely rich; o2 sensors both check
good and switch well. MAF 2495Hz at idle;map is within parameters as is TPS. Checked purge
operation and fuel pressure ,all within spec. Car ran very well after repairs until engine got hot
then ran rich;hard start no codes.
Answer:
That Mass Air Flow Sensor reading is way out of range, especially at idle. I would start by changing the
MAF and seeing how it runs hot after that. They have been known to cause a lot of odd problems on
the 3.8 engines. If it's running extremely rich, I would first check to see if the fuel pressure regulator is
leaking by removing the vacuum hose attaching to it. If it's bad, additional fuel will get sucked into the
intake and cause a rich condition. A leaking fuel injector, or stuck open fuel injector will cause this
issue too. It seems just about everything else has been replaced, so there can't be m
