Why Your Oxygen Sensor Shouldn’t Be Ignored

9 Oct

If you’ve noticed your car performing inconsisently, can’t pass inspection due to poor emissions performance, with poor fuel economy, or running like a raped ape somedays, and like a 3 legged dog on others, it could be a faulty oxygen sensor. The 02 sensor is partially responsible for telling the ecu what to do and when. When they are new, 02 sensors relay accurate info very quickly to the ecu. When they age, or get contaminated, they act lazy, slowly relaying info, and performance and economy suffer as a result. We offer a full range of direct replacement 02 sensors from Bosch and Denso, 2 of the largest OEM suppliers in the automotive world. In fact Bosch invented the 02 sensor! These are plug and play, not some cheesy universal joint you’ve got to spend timing soldering in. Waterproof connections ensure years of reliable service. No sense paying the dealer more for the same part in a different box!

So why is it important to replace? As the sensors age, they get contaminated. Remember, these sensors sit right in the catalytic converter and the exhaust pipes, so they are forced to live in a dirty, nasty environment. As time goes on, contaminents build on the sensor itself, and it’s no longer able to react with the speed that modern ecu’s demand. These contaminants also can cause false readings to the ecu, causing the car to run significantly richer, or leaner, than it should. This can have systemic results in other areas of the car. Not only will you get poor performance and poor fuel economy, overly rich conditions can clog cats and cause injectors to stick open. Overly lean conditions can wreak havoc on your internals causing knock, as well as potential piston damage.

If you run race gas, methanol or alcohol injection, this can also cause premature 02 sensor failure. Thankfully, these sensors are affordable, and very easy to replace yourself

None of us here have a Porsche, but they have had such an impact on the world of sports cars, we can’t help by write about them. The 911 is one of the iconic sports cars of the modern era. There have been so many versions, one offs, projects, concepts, it is dizzying. One such model is the 2.7RS – the original bad boy that has eventually spawned such versions as the Carrera CS, and the modern day GT3 and GT3RS.

Porsche first debuted the model at the 1972 Paris International Auto Show. It was one of those times where Porsche had to build a certain number of production versions in order to enable the race version to participate in Group 4 competition. Such homologation specials are fairly commonplace for Porsche.

Everything about the RS was a 911 on a diet. Everything was thinner. The sheetmetal, the glass, even the carpet. These cars generated about 210 hp in standard form, and were offered in a few different trims for street use, club use, and full out race use. They were, of course, a limited run, and when they change hands now, they go for hundreds of thousands of dollars. Many people now choose to do replica versions, where they take a clean shell, and do a version in the spirit of the original.

No color is impossible

964 series 911 C4 Lightweight – sort of a mix of a few different models put together by the Weissach factory. Just 20 made worldwide, and I’m told MSRP was over $150k when new.

This rare beast weighed in just north of 2400 lbs. Featured adjustable differentials

This particular one had extremely low miles – just over 5000km’s from new! Love the rarity of it, but it was designed for rally use – not quite sure I’d want to go blasting down the trails with such a rare, expensive beast. Probably why it has such low miles and in is such immaculate condition!

Rare Stuff Part 2

21 Dec

Next up is another Porsche, this one a bit more attainable (and one of my personal favorites of all time).  This clean 996 GT3 RS was never officially sold in the US.  Featured a naturally aspirated version of the famous 962 and GT1 cars.  While this is a street car, designed for track days and such, the racing versions dominated at LeMans, and throughout the FIA GT3 class during the years it raced.  Quite a pedigree!  Yours for a cool $100,000US.

I have a bunch of cool videos saved on my computer with 996 GT3 RS’s racing at various tracks.  If you guys are interested, let me know and I’ll post them!
