Smog Check: McLaren Mercedes Benz SLR

star-smog-check-mclaren-mercedes-benzYet another gorgeous vehicle from the Griffith Racing Team. This black beauty is probably one of the most expensive cars that we’ve ever tested.

From Wikipedia: The Mercedes-Benz SLR McLaren was inspired by the Mercedes-Benz 300 SLR Uhlenhaut Coupe & Racecar of 1955,[2] which was a modified Mercedes-Benz W196 F1 race car. It was introduced on 17 November 2003. On 4 April 2008, Mercedes announced that they would cease production of the SLR. The last of the coupes rolled off the production line at the end of 2009 and the roadster version was discontinued in early 2010.

Star Smog Check: Aston Martin Vanquish & 1978 VW Bus

smog-check-aston-martin-vw-bus-huntington-beach.jpg

Our smog technicians are inspecting two very different vehicles. The Aston Martin Vanquish passes it’s star smog check. Unfortunately, the 1977 Volkswagen Bus does not. It is sometimes difficult for older vehicles to conform to the strict smog standards set out by the State of California. On the bright side, California offers subsidized smog repairs for low-income motorists. There is also a vehicle retirement program that will give you cash for your “clunker.”

Help, My Car Failed a Smog Check. (High HC Failure)

Solving Exhaust Gas Failures: High HC

Failure to achieve a pass on HC emissions is usually due to an excessively high ratio of fuel to air, thus causing high levels of unburned HCs. Start by checking the following in the order suggested here.

1: Spark plugs & wires
2: Timing spark/advance
3: Vacuum leaks
4: Other ignition problems
5: 02 Sensor
6: Evaporative fuel system

Plus…Fuel Injection system, Air/fuel mixture adjustment, PCV system, Catalytic converter(s), Throttle position sensor, MAP sensor, MAF sensor, Other sensors/switches, Computer PROM, Internal engine repair, Other repairs/unknown.
