What is the difference between RCJ6Y and RCJ8Y?

Joe Ford

What is the difference between RCJ6Y and RCJ8Y?

Champion makes a wide range of spark plugs, including the RCJ6Y and the RCJ8Y types. The only difference between plug RCJ6Y and RCJ8Y lies in their heat ranges.

What does the Y mean on a spark plug?

The letter “Y” indicates a V-grooved center electrode. The number after the – indicates the recommended spark plug gap in tenths of a millimeter.

What do the letters and numbers mean on Champion spark plugs?

The combination of letters and numbers assigned for every Champion spark plug is a logical formula which indicates the major features of its design. [15] Heat Range – The middle number indicates the heat range of the spark plug, the higher the number the hotter the heat range.

What does NGK stand for?

What do the letters and numbers mean on NGK Spark Plugs?

The heat rating is a measure of the amount of heat dissipation. The heat range of a spark plug is the range in which the plug works well thermally. The heat rating of each NGK spark plug is indicated by a number; lower numbers indicate a hotter type, higher numbers indicate a colder type.

What does white tip spark plugs mean?

Blisters on the insulator tip, melted electrodes, or white deposits are signs of a burned spark plug that is running too hot. Causes can include the engine overheating, incorrect spark plug heat range, a loose spark plug, incorrect ignition timing or too lean of an air/fuel mixture.

Can old fuel cause a misfire?

Consequently, bad gas is good for the repair business. When people use gasoline that does not keep their fuel system clean, their injectors gradually clog up with varnish deposits. This results in a lean fuel mixture that may cause the engine to misfire, idle poorly, and hesitate or even stall when accelerating.

What caused the oxygen sensor failure?

Why an Oxygen Sensor May Go Bad Over time, an oxygen sensor may become caked with byproducts of combustion, such as sulfur, lead, fuel additives, oil ash, etc. This contamination causes the sensor to lose its ability to produce voltage and send the right signal.

Can fuel pump cause shifting problems?

The cause may not be the transmission and instead could be the result of air or fuel distribution issues or faulty sensors. A lack of fuel pressure from a failing fuel pump or pressure regulator can also result in poor acceleration. Struggling fuel pumps starve the engine for fuel, resulting in poor acceleration.

What are the signs of a faulty fuel pump?

Symptoms of a Bad Fuel Pump

  • Car Won’t Start. There are a host of issues that could prevent a car from starting, but a lack of fuel is one of the first things to check.
  • Sputtering.
  • Car Dies Under Heavy Load.
  • Inconsistent and Unintended Acceleration.
  • Decreased Fuel Efficiency.
  • Increased Engine Temperature.

What are signs of transmission going out?

The top signs why your transmission may be failing:

  • Transmission won’t engage or stay in gear.
  • Shifts are delayed or missing gears.
  • Transmission slipping or engine is revving high.
  • Transmission fluid is leaking.
  • If there’s a burning smell.
  • If there is buzzing, clunking, humming noise.
  • Car has no power.
