How do you fix a Toyota Camry 1992 V6 with high hydrocarbon?

Answer 1

High hydrocarbon emissions from a vehicle may be caused by improper ignition timing, faulty ignition, misfiring problems, vacuum leaks, worn piston rings or valves or an exhaust gas recirculation system incorrectly operating at idle. One fouled spark plug can result in extremely high hydrocarbon emissions. You car is 14 years old and probably has high mileage. Start by replacing the spark plugs and plug wires. Replace every single vacuum line under the hood. Replace them one at a time, so as to not get confused. Clean you EGR Valve of any carbon deposits, and make sure it is functioning correctly. Pour a can of a good Fuel Injector cleaner such as Seafoam or Techron in a full tank of fuel. Leave the cheap stuff on the shelf, as is does very little good. To remove built up carbon deposits, inject it through the intake by following the directions on a can of Seafoam. Have someone check the timing on this vehicle. A compression check will verify if you have worn rings or a burnt valve.

Answer 2

To address high hydrocarbon levels in a 1992 Toyota Camry V6, start by checking and replacing the spark plugs, spark plug wires, and air filter. Make sure the engine is properly maintained and in good working condition. Additionally, consider performing a fuel system cleaning and an emission system inspection to identify any potential issues causing the high hydrocarbon levels.
