Every experienced mechanic knows that troubleshooting car repairs is as much about instinct as it is about technical skills. But when he started the car, the CheckEnginelight began flashinga sign that something was seriously wrong. I had never seen a flashing CheckEnginelight before, Hugo admitted.
Service bulletins, more formally known as Technical Service Bulletins (TSBs), are documents issued by vehicle manufacturers to alert technicians to common issues found in specific makes and models. Unlike recall notices, TSBs typically address non-safety-related defects, from software glitches to persistent checkenginelight triggers.
An engine misfire occurs when one or more cylinders in the engine fail to complete the combustion process properly. This disruption can cause the engine to run rough, lose power, shake, or trigger the checkenginelight. Engine warning lights illuminated. Poor fuel economy.
As a car owner, one of the most dreaded moments is when the checkenginelight suddenly turns on. However, instead of panicking, take a deep breath and understand what your car is trying to communicate through that little orange light. Pay attention to other symptoms your car may exhibit and the checkenginelight.
Faced with the dreaded CheckEngineLight (CEL)? While it’s easy to jump to the worst conclusions, sometimes your vehicle may simply trigger the CheckEngineLight for gas cap issues. Let’s understand the connection between a bad gas cap and the CheckEngineLight and how you can fix it.
However, “anything” really only meant vehicles made by General Motors, Ford, and Chrysler. With a limited number of vehicle brands to learn, it didn’t take long to become proficient in all areas of automotive repair, from engine mechanical, drivetrain, electrical, steering, suspension, and all other systems. That was back then.
And, with the Ford V8, as the engine ages, reduced oil flow to the cam phasers will impact the timing system.

Older vehicles may have only a single ignition coil with a distributor and spark plug wires connecting to spark plugs. Also, check the spark plug socket and wiring harness. Reattach the engine cover. Start the engine and take the car for a test drive. Technically, no, but in truth, it’s much SAFER.
This reduces fuel pressure and prevents the fuel injectors from delivering enough fuel from the fuel pump to the engine. A clogged fuel injector, fuel filter, or intake valve may also cause an engine to misfire and trigger the checkenginelight. Fixing a car that shakes when idle requires some technical know-how.
And if you see the ominous checkenginelight , it’s a clear sign something’s amiss in the combustion chamber. Here’s how a rich or lean fuel mixture may impact your engine: A. In older vehicles with carburetors, a lean condition can be caused by blocked jets. Can You Drive With a Lean or Rich Engine ?
Do you also see suspicious red-colored fluid puddles under your vehicle? The cost of replacing a gasket in these vehicles is higher than in a manual transmission car. Thats why you should have a mechanic check out your car at the first sign of trouble. You also need good technical knowledge to diagnose the issue correctly.
Declined fuel efficiency: Any glitch in the variable valve timing system can cause increased fuel consumption and a drop in engine power. This happens when a bad VVT solenoid can’t adjust the engine’s timing for optimal air-fuel mixture. Your engine then uses more fuel than necessary. Have more questions? Let’s address them.
Starting Issues Since a failing fuel pump won’t send enough fuel to the engine, you’ll face difficulties starting your car. Lit CheckEngineLight A bad pump will cause an air-fuel mixture imbalance, which will trigger the CheckEngineLight. These use a fuel injector to supply fuel to the engine.
The light could be triggered by: Low fluid level: Driving with low transfer case, transmission , and other fluids can overheat AWD components and wear them down faster due to a lack of lubrication. This can trigger the AWD warning and CheckEngineLight. Refill them if running low, or replace them if they’re old.
Engine misfire: Frequent misfires are a clear sign that your fuel injectors aren’t supplying enough fuel to the cylinders, disrupting the combustion process. CheckEngineLight: If the CheckEngineLight comes on , it could signal that your fuel injectors need attention before things worsen.
Get a free quote It’s funny though, sometimes a Christmas tree reminds me of my days at the repair shop when one of my rather animated coworkers would use it to describe a vehicle with a lot of warning lights on: “Wow, this instrument cluster is lit up like a Christmas tree!” I can do without.”
Letting Your Car Overheat This is a grave mistake any vehicle owner could make. Internal combustion engines generate a lot of heat and require a cooling system to work efficiently. If your car gets too hot, you can blow a head gasket , warp a cylinder head, or cause irreparable engine damage.
Accessibility : In some vehicles, the spark plugs and wires are easily accessible, while in others, they may be difficult to access, which increases the labor costs. For instance, in V6 and V8 engines, spark plugs are located at the back of the engine or underneath the intake manifolds.
A “ Reduced Engine Power ” or “ Engine Power Reduced ” warning means your engine isn’t working at full capacity. When the light comes on, vehicles go into “ limp mode ” — a protective state that reduces engine power, limits the transmission to lower gears, and restricts RPMs to protect the engine.
This small yet essential part can throw a wrench into your vehicle’s well-being when things go south. Surprisingly, diagnosing issues with this engine component is easy if you pay attention to the bad idler pulley symptoms. You may also notice the CheckEngineLight illuminate on your dashboard.
They’ll then turn the key to the ignition switch ON position without starting the vehicle and wait between 5 seconds and 10 seconds for the dashboard lights to turn off. Then, the mechanic will turn on the vehicle and let the engine run at a stable idle speed for 15 minutes. Not to worry.
