Our vast experience allows us to recognize things in the field because we've seen almost all of them before. If you've got issues with your vehicle and it's not running right or making weird sounds, call us right away. We'll get you squared away so you can have confidence that you won't get stranded on the road. Here are some of the things we see and repair often.
Strange Engine Sounds or Knocking
If you hear knocking or other strange sounds coming from your engine, that could be an indication there's a serious problem coming your way. Engine knocks often occur when the timing is off, preignition is happening, or the engine is running lean. In any event, get it checked out as soon as you can. Mobile Mechanic Master understands auto problems and the trouble signs that unusual sounds can mean and how to fix them.
Noticing a loss of power is another telltale sign that you have an engine problem. These power loss types of issues usually show up when accelerating from a stop or when trying to pass another car. The power loss can cause a hazardous situation and is something to be addressed promptly. Our mobile auto service for the city of Orange and adjacent cities will allow you to have an experienced mechanic get to the bottom of your issue fast.
A vehicle that emits smoke is telegraphing to you that there's a problem. It can be due to a number of factors like a blown head gasket, cracked head, excess piston and piston ring gap, bad fuel, failing sensors, and more. It will usually be accompanied by a poor running condition.
Check Engine Light
Your check engine light monitors a myriad of things that contribute to your engine running properly. From the correct fuel mixture to ignition and spark problems to problems with your catalytic converter, this important gauge light often turns yellow or red or blinks to let you know the severity of the problem. Ignoring this signal can cause a small problem to become a big expense. For example, a lit check engine light could mean that your oxygen sensor has recognized that your air/fuel mixture is lean or rich. Addressing the issue promptly could be a minor expense, but ignored could cause damage to the catalytic converter costing thousands.
Common engine misfiring causes are faulty or fouled spark plugs, a cracked distributor cap, a lean air/fuel mixture, low compression, or a slipped timing belt or chain. When an engine misfires, the spark is igniting the compressed fuel gasses in the cylinder at the wrong time. Multiple cylinder engines operate like an orchestra. The timing of each cylinder's fuel mixture explosion has to be just right so that all the pistons work in perfect harmony. When that timing is off (either the explosion is too early or too late) the piston that's connected to the crank is being driven down in the cylinder at the wrong time and often in opposition to the timed explosion of other cylinder's fuel mixture explosions. Depending on the severity (how bad the timing is off), this can cause serious damage to your engine.
Make sure you seek out the professionals at Mobile Mechanic Master to determine what your car's misfire cause is and get it repaired promptly.
Backfires are a condition caused by a lean fuel/air mixture. When your car has a backfire, those gasses are exploding outside of your engine's combustion chamber. This will damage the exhaust and intake systems and also will give you really poor fuel economy. You'll definitely know when you have a backfire condition as the noise is like firecrackers going off especially at deceleration.
Newer cars have all kinds of sensors that monitor all the critical functions having to do with the operation of your vehicle. When these sensors get tripped, a warning light is often tripped which usually means that there's a problem that has to be addressed.
The common sensors are:
- MAF(Mass Air Flow) Sensor
- Temperature Sensor in the combustion chamber
- Engine Knock Sensor
- Engine Crankshaft Position Sensor
- Temperature Sensor/Mid catalytic on the Catalytic Converter
- Oxygen Sensor on the Catalytic Converter
- Exhaust Air Temperature Sensor
- Throttle Position Sensor
