oga Sir, rough idling or poor engine performance does not need you to change every thing in the car.eTroubleshooting must be considered with steps to pinpoint concerns. Secondary check to primary cause..


  1. Air cleaner condition
  2. Check for air leak
  3. Foul sparks plugs/coil
  4. Fuel pressure/clog fuel filter – weak fuel pump
  5. Emission control input sensor – Scan will determine that.

NOTE: The use of wrong spark plug on cars will even reduce more the engine performance. Because it is out of heat range specification which in turn affects the coil.

you could be having electrical leakage from the coil. or an air inflow problem. these are my two thoughts. open the hood in the night and open the engine cover. start the car and check for sparks… that’s sign of electrical leaks. if fixing that doesn’t work, get a mechanic to check your air filters and the air intake valve.

Every vehicle should have its engine tuned up and decarbonized every 20000miles. This is exactly what you should do to solve this problem.
