Energy absorbing hitch cover introduced

Mohr Bumper Shield

Go Ahead - Bump This! Mohr Manufacturing Introduces A Crash Tested, Energy Absorbing, Portable Receiver Hitch Cover And Bumper Shield / Skid Plate.

The two most frequent vehicle accidents are getting hit while parked and the rear end collision.  This crash tested, energy absorbing hitch cover not only covers your ugly receiver hitch, it works as a bumper shield for rear mounted 2” receiver hitches and doubles as a skid plate and bumper shield for front mounted receiver hitches.

Its 12” wide by 6” high only sticks out 4” beyond your receiver hitch (in the full compression mode), crushes 2” when hit, won’t interfere with most vehicles equipped with backup alarms and can be used in the down position (shown) to protect against under-ride on full size pickup trucks or SUVs or flipped around to protect against over-ride on small size SUVs.  

It has a duel compression system so it can be pinned out for maximum protection or pinned in closer (still energy absorbing) for approach angle clearance during off-road use, tight garage spaces or to avoid being detected by backup alarms.  Simply arrange the rubber bumpers / spacers and pin it where you want.   

Because it’s energy absorbing it won’t transfer all the crash energy from a rear end collision directly to the occupants, will keep your receiver hitch from bending when hit from the rear (unlike all other static receiver hitch products – including your ball mount), keeps Braille parallel parkers from wrecking your bumper, reduces whiplash if hit hard enough and has a lifetime crash warranty (like all of our other products) – if it bends or breaks from a rear end collision, at any speed, it will be replaced absolutely FREE.

Your Vehicle's Oxygen Sensor

Your Vehicle's Oxygen Sensor - the Watchdog of Harmful Emissions

BROADVIEW, Ill., April 21 /PRNewswire/ -- If you are concerned about your car's carbon footprint, it's important to know that your vehicle's O2 sensor (oxygen sensor) plays a key role in sounding the alarm if excessive harmful exhaust emissions are coming out the tailpipe.

"A properly functioning O2 sensor plays the role of a watchdog when it comes to monitoring your car's exhaust emissions, especially hydrocarbons and carbon monoxide," said Warren Suter, Director, Engine Management Systems for Bosch, which developed the automotive oxygen sensor in 1976. Bosch is the world's largest supplier of automotive parts and systems. www.boschautoparts.com.

The O2 sensor measures the oxygen in the exhaust and signals the engine's computer to adjust the air-fuel ratio to ensure that combustion is as complete as possible. This continuous process optimizes engine performance and fuel efficiency and reduces harmful emissions. A vehicle, depending on the make, model and year, can have between one and four O2 sensors at various locations in the exhaust stream.

If an O2 sensor is worn out and fails to assess the air-fuel ratio accurately, the engine's computer tries to accommodate the perceived variation and, in the process, may adjust the mixture to be too lean or too rich. The result? Harmful tailpipe emissions and possible damage to the catalytic converter and other engine components.

Cheap Trick: Improved stopping power

My desire has been to retain my jeep as close as possible to stock to ensure that I can always find the necessary repair parts without excessive time delays.  My jeep in many respects is far from stock as it does sit on 35-inch tires.  With the shift to bigger tires, stopping ability was a noted downside.

Not ready for the expense of a Vanco brake up-grade, I opted to start with new brake pads by installing the ones used by racers: EBC Brakes.

The EBC brake pads are ceramic/kevlar fiber material and a direct replacement for the stock brake pads.  EBC provides brake pads that will fit a wide range of applications.  For my Wrangler, I opted for the Series 4000 (Yellow Stuff) pads as they are advertised as being the “...most grippy pad formulation”.  While designed for closed circuit racing, the pads can be used on highway.

After about 500 miles of use, I can say that stopping ability has been improved and the cost was reasonable.

4x4Wire Tech Hint: "Check Engine" Light

"Check Engine" Light

Vehicles manufactured since 1974 began sporting a variety of engine and emission control systems.  As the engine control and monitoring systems became more complex, on-board diagnostic systems were developed to record fault codes and assist in problem diagnosis.

In general, all vehicles equipped with on-board diagnostic systems (OBD-II is the current standard) will store error codes that can be read using a portable code reader or scanner.  A "Check Engine" light comes on to indicate that the engine management computer has detected a problem related to emissions or engine operation.  It is your notice that something needs to be fixed in order to comply with federal emissions requirements or to keep your engine running.

Many of the trouble codes relate to engine or emission sensor inputs that have failed or are out of tolerance.  The sensors control the "engine management computer" and keep the engine running at optimum efficiency.  Failed or out of tolerance sensors mean your engine is not operating at optimum efficiency.

While it is easier to read the fault codes with a code reader/scanner, most vehicles provide an option to display the codes without a scanner.  

To view the error codes, start with the engine turned off (Ignition Key in the OFF position).  Turn the ignition key to the "ON" (not "IGNITION/START") position, then turn it off for about a second.  Turn it on for a second, then turn it off for a second.  The third time you turn it on, trouble codes should begin flashing on the odometer display.  (NOTE: this process works with newer Jeep vehicles.  It may or may not work with out models.)

Once the error codes are recorded, interpretation will indicate the likely source of the fault.
