hey there car owners today I want to
0:01
talk about something critical your car's
0:03
brain also known as the engine control
0:06
module or ECM this tiny yet powerful
0:09
component controls essential functions
0:11
like fuel injection ignition timing and
0:14
overall engine performance when it
0:16
starts failing it can spell trouble for
0:18
your car and your wallet so let's dive
0:21
into the most common symptoms of a
0:23
failing ECM and why you shouldn't ignore
0:25
them first up the check engine light
0:28
we've all seen that dreaded light pop on
0:31
but if it stays on even after repairs
0:33
that's a major red flag it could mean
0:36
the ECM is misinterpreting sensor data
0:38
or failing to clear the error a mechanic
0:41
might reset it but if the light keeps
0:42
returning you might have an ECM issue on
0:44
your hands next let's talk about engine
0:46
misfires stalls or rough idling ever
0:49
been at a traffic light and your car
0:51
starts shaking or even stalls
0:52
unexpectedly that's often tied to the
0:55
ECM it controls fuel delivery and Spark
0:57
timing and when it's not working right
1:00
your car's performance becomes
1:01
unpredictable I've seen cases where
1:03
drivers thought it was just bad spark
1:05
plugs only to discover the real culprit
1:07
was the ECM now on to fuel economy a
1:11
faulty ECM can mess with the air fuel
1:13
ratio causing your car to burn more fuel
1:15
than it needs if you find yourself at
1:17
the gas station more often without a
1:18
clear reason your ECM might be wasting
1:21
fuel it's a subtle symptom that many
1:23
Overlook until it starts hitting their
1:25
budget hard another sign is difficulty
1:27
starting the car imagine being stuck in
1:29
in your driveway turning the key but
1:31
your car just won't start this happens
1:33
when the ECM doesn't communicate
1:35
properly with the ignition system
1:37
sometimes it'll crank but other times
1:39
it's completely dead frustrating right
1:41
and lastly sudden loss of power or
1:43
performance one of the scariest symptoms
1:46
is losing power while driving you press
1:48
the gas but the car doesn't respond as
1:51
it should this can happen randomly and
1:53
can be dangerous especially on highways
1:56
drivers often confuse this with
1:58
transmission issues but a bad ECM can be
2:00
the root cause the bottom line don't
2:03
ignore these signs a failing ECM can
2:05
lead to costly repairs down the line if
2:08
you notice any of these symptoms get
2:10
your car checked by a professional to
2:11
avoid further damage it's always better
2:13
to catch these issues early than face a
2:16
complete breakdown on the road that's
2:17
all for today stay safe and keep your
