Haven’t visited TTAC in a while but I’m back! My Mazda 6 has now crossed the 101k mileage marker and all your nuggets of wisdom have helped keep this classic functional and beautiful. However, there’s another problem rearing its head that has plagued even the Mazda forums I’ve visited for a resolution.
It involves the car’s driveability at anything below 3000 rpm. Doesn’t matter whether the engine is just warming up or at operational temperature, the car will hesitate (sometimes violently) in a stuttering/bucking fashion when accelerating from a stop through the gears until I crest that magic 3000 mark on the tach. Out on the highway, passing in top gear is almost impossible because of the engine’s hesitation if revs fall below that number, requiring a downshift to 4th to keep them up. At first I thought my manual skills were to question but then I never started experiencing this issue until around the 87,000 mile mark. It has since gotten worse. Sometimes the bucking is enough to trigger the CEL but then it always goes away after a while.
Browsing the forums I’ve tried everything from cleaning the MAF sensor, fuel injector cleaner, throttle body cleaning as well as replacing the O2 sensor. I’ve narrowed it down to either spark plugs (some forum members replaced theirs but the problem came back hours later), the coils or possibly a vacuum leak. One post I read indicated a potential cylinder misfire. Even Mazda dealers were confounded. (Read More…)
Outside North America, this little blue pill of an A-segment car is known as the Daewoo Matiz Creative. It may look an obsolete computer peripheral (or a pregnant roller skate), but GM claims that the Chevrolet Spark has more torque than a Ferrari 458 Italia. As a self-described technology lover, and card-carrying resident of the Left Coast, I had to check it out.
I have a Piston Slap question: Most of the gasoline sold here in New Mexico is high altitude gas, meaning that Regular is 86 octane, Midgrade is 88, and Premium is 91. The owner’s manuals for my ’06 Corolla and my wife’s ’08 Hyundai Tucson (try not to be jealous :-) ), calls for 87 octane fuel. Am I OK to use Regular or should I take the manuals at face value and pay a dime more per gallon for Plus? (Read More…)
Prepare for a low intensity price war over electric vehicles. GM announced that its all-electric Chevrolet Spark, going on sale next month in California and Oregon, will sell for as low as $19,995 after the full federal tax credit of $7,500. According to the calculations of Reuters, that’s “as much as 38 percent less than what it takes to buy its larger sibling, the hybrid Volt.” (Read More…)
Chevrolet today announced it will produce an all-electric version of the Chevrolet Spark mini-car – the Spark EV. It will be sold in limited quantities in select U.S. and global markets starting in 2013, including California.
A123 Systems will supply the advanced nanophosphate lithium-ion battery packs that will power the Spark EV. Details on specific markets, range, quantities and pricing will be announced later.
If you have a pulse and a willful ignorance of the local speed limit, you’re probably not interested in the Chevrolet Spark. If you’re a media-savvy hipster who’s on Facebook sixteen hours a day, you’re probably not interested in the Spark, either. If you’re a techno-geek or an eco-geek, you’re probably still not interested in the Chevrolet Spark.
If you need something to get you from point Alpha to point Beta and aren’t willing to pay too much, you might be interested in the Spark. But only after all the alternatives have been removed from your short-list as being too sensible. And even then, a lobotomy might be required to help you make up your mind.
That’s a shame, because the Spark isn’t really that bad.

GM’s plan to develop an electric version of its (previous-generation) Chevrolet Spark city car for developing markets had been dependent on a joint development deal with REVA, the Indian firm responsible for such vehicles as the REVAi (known to Brits andTop Gear fans as the G-Whiz). But with the AP [via BusinessWeek] reporting that Mahindra & Mahindra has bought a 55 percent stake in REVA, GM’s deal to use REVA’s technology in its Daewoo-developed hatchback appears to be off. GM had already scaled back its cooperation with REVA, delaying the planned release of the Spark EV and focusing on fleet testing the car. But, says GM India President Karl Slym
Now we’ve stopped the test fleet as well. We were doing it purely as something to learn. Now there’s no real benefit to that. We may as well stay with the GM solutions.
While India is still waiting (and waiting, and waiting) for volume production of their ballyhooed Nano, the cars-for-pygmies segment is in overdrive in neighboring China. It’s hard to keep them apart. When Chery launched the QQ in 2003, taking a bit more than just design cues from the Daewoo Matiz (a.k.a Chevrolet Spark) Car and Driver called the QQ a “carbon copy.” GM called their lawyers. After three years in court, the spat led to nothing, except that Chery can’t sell cars in the US under its own name due to the similarity between “Chery” and “Chevy.” In the meantime, the QQ is a runaway hit in China. Hits attract admirers. There’s a new copy in the house! (Read More…)
