Have it checked for codes. There will be a misfire code that will let you know what cylinder has the problem.
If your check engine light is blinking that means an ignition misfire has been detected
the check engine light is blinking and my 03 Nissan exterra is running rough
you have a cylinder misfire
Have vehicle scanned to determine the problem Possibly a bad ignition coil
why is my ford sport trac run rough at idling. Being that the check engine light is on, start with having the codes read. Your local auto parts store can help with that at no cost.
disconect battery for about a minute that will turn the light off and put some stp fuel system cleaner or seafoam in your gasoline
There are many symptoms of a bad O2 sensor. Some are poor fuel efficiency, flashing check engine light, the failure to pass a smog test, and rough idling.
Rough idling is whenever the vehicle's motor "misses" or does not fire causing an imbalance and a loss of rotation reducing the motor's power and causing excessive shaking.
The check engine light should be on and give you a code. If not and your vehicle is idling low or rough you should take it off and clean it out before you spend money on it. A good cleaning will usually fix that problem.
because of ignition coil faulty.due to mountings,abnormal fuel pressure.
When the check engine light comes on the computer sets a diagnostic code. Most auto parts stores will read the code for free and tell you what to replace to fix the issue.
