How about timing? How about the distributor and rotor? What about the timing chain?

My car tried to shut off going down the highway. Then it was shaking mildly. engine light came on flashing.This is a 1999 Dodge Stratus- 4cyl.-2.7 engine


The flashing engine light means the miss is bad enough to cause damage to the catalytic converter. The check engine light does not involve engine oil.
Are you saying the timing belt is not turning the cam ?

Aveo 2006 has an Engine light ON and Car is shaking when trying accelerate. Car is not been able to pick up the speed with putting full pressure on the accelerator.


Yeah, it's worth it. Probably a coil pack. But this is a guess. When you take it to a garage and they diagnose it. They tell you this is the fix. They are liable.

Why is my car shaking


Short answer: If it quits shaking when you let off of the gas pedal, it is likely an engine misfire.

Long answer: I believe your model is new enough for the transmission to have a lock-up torque converter.
At around 40-45mph, the torque converter locks, making a solid connection between engine and transmission.
When this happens, any engine misfire is more readily felt throughout the car during acceleration.
The first items to check would be spark plugs, spark plug wires, and ignition coils. These are most likely to act up under load conditions such as acceleration.

On the other hand, if you let off of the gas pedal and the car still shakes, it is probably a tire or wheel problem.

Hyundai Sante Fe 2003 with automatic transmission and 3.6L engine shutters and shakes when slowly accelerating to about 60 kmph. If you take your foot off the gas or accelerate the shaking stops...


Tune up spark plugs, wires, check fuel filter, etc... Check distributor, change transmission fluid and coolant. If you need a new distributor I would try looking for a used one online.

Car shaking, no acceleration, check engine light on


Year make and model ??
You would need to have the computer scanned for the trouble codes. Was the engine running ok before you replaced the plugs and wires ?
Could have crossed two wires to the wrong cylinders ?

Mazda millenia 2000 2.3L S, is shaking while accelerating and very bedly shaking after rain


Could be weak spark plug wires or cap and coil. Electricity will jump to ground instead of thru the spark plugs if the wires are wet.

Volkswagen 2006 Jetta, shaking while driving and accelerating.


Retrieve the trouble codes and fix any problems. if you dont have acces to scanner there are places out there that will scan it for free. Know, however, that just scanning it it's not a diagnosis. Fix the leaks, change the oil and add propper amount and type of oil. The shaking of the engine could be due to misfires causing the vehicle to run rough but in order to find out you need to retrieve the trouble codes. Best bet is to take it to a shop and have it diagnosed.

Jerking/jumping while driving


An automobile's ignition system may work fine while idling but fail during acceleration. Problem areas to be inspected include the spark plugs, spark plug wires and vacuum hoses. Car owners should look for spark plugs that are covered in oil or sediment or damaged, spark plug wires that have damaged insulation, and vacuum hoses that are unplugged or leaking. Fuel Problems
  • The use of a fuel additive that contains both fuel injector cleaner and water remover can fix minor problems due to water in the gas and fuel injector clogs. A fuel pressure gauge can also be used to test the injection system to assure proper pressure.
While most acceleration problems are likely caused by problems with the plugs, wires or fuel, a variety of sensors and other components can cause similar problems. a bad tps ( throttle position sensor ) will cause causes transmission shift issues, bucking, jerking, idle surging, engine cutoff, hesitation on takeoff, and surging while going down highway.
good-day ! check and or clean maf sensor if need be. you can by the maf sensor cleaner at most auto parts stores.
