What is the deal with minivans? I was thinking the other day that as an outdoor person, minivan’s are perfect. They have lots of room for people and gear, AWD (in some cases), lots of roof space, and better MPG’s than an SUV. But apparently I can’t own one because they’re not cool. I could get a wagon though. Isn’t a minivan just a super-sized wagon?

Will minivans ever be cool to own?

A Mark VII is in my sights.  I like the Mark VIII air suspension control that lowers the car when it hits 60 mph.  Will a Mark VIII suspension control box work in a Mark VII?

Yesterday’s post on Texas Tailgate Theft definitely struck a nerve with this Native Texan, especially the NCIB’s Quote:

“Since a tailgate theft takes just seconds to accomplish, consumers might consider using an after-market security device, such as a hinge lock to thwart criminals.”

Yeah, not quite…

I read your plea for questions, so I’ll lob you a softball. Why has my 2005 Maxima’s TPS decided to randomly poop out on me after doing a warm start?

Specs: 2005 Nissan Maxima 6MT. 135,000 miles. Electronic throttle. Stock air intake + (new, put in the first time the TPS acted up 3K miles ago) K&N filter. The car’s now on its third owner, having spent its whole life in Evansville, IN, Lexington, KY, and now Louisville, KY. At the rust belt’s frayed fringe, I guess. No surface rust anywhere on the car, though. Electrically speaking, it’s in good shape. (Save the rear ABS sensors… a rant for another day)

Hi Sajeev,

So I like my new 2010 Miata Touring (second car and half time daily driver), and picked it because it looked good on the side of the road by my house, low miles (19k), priced OK(mid 14′s), I had the dough saved up for a bike and I am happy with the current Vstrom, and last but not least it is an automatic. The OEM suspension seems firm to me but obviously not race ready. Roads in Northeast are usually not-so-new ranging down to horrible. Miata people say its mushy and floaty, those who want to autocross or race. Read More >

Hi Sajeev,

I do a more through job at the time of purchase, but every year after I do a drain/refill on the radiator and replace some transmission fluid by using my fluid extractor to vacuum up as much ATF as possible through the dipstick tube.

I know that I’m not getting all the fluids exchanged this way, but my question is how much of a positive impact is this regiment actually having on my cars? Am I just wasting my time? I haven’t suffered a mechanical failure since I started doing this, but I don’t know if that proves much.

Keep in mind that the vehicles I tend to own are 20 to 30 years old.

Hey Sajeev, I got one for you.

Several engines nowadays are set up to operate on half their cylinders under light-load conditions. Would the design considerations for piston rings vary from those normally used for such cylinders that are only used part-time? The question arises in the context of a 2009 V6 Accord that is currently in the Honda dealer’s shop to have the piston rings replaced at the manufacturer’s expense to cure a continual oil consumption and spark plug fouling problem.

Hi Sajeev,

I have a question about driving style that I’d like to pose to you and the B&B. Part of my highway commute is a steady 2 mile grade. With a running start of 75 mph, my 2007 Mazda B2300 slows to about 62 mph by the top of the hill when I keep it in 5th gear, with the engine turning about 2000 rpm. I can maintain 70+ if I drop into 4th and floor it, but I’m a cheapskate at heart. My question is, is it really more efficient to lug up the hill in top gear, or am I just kidding myself and doing irreparable damage to my engine? Read More >

When my scan gauge says my engine is under 99% load, and I’ve only pushed the gas pedal about halfway down, does that mean, as I suspect, that I can floor it and I’m not going to get more than a drop more power out of it? 

And, in a modern car (’08 Civic, stick), will the computer control prevent me from wasting gas by pushing the gas pedal beyond the point where I’ve reached 99% load?

Good afternoon Sajeev,

Read your latest and I’m determined to help you out. I recently had a bone-stock 87 CRX Si follow me home from an impound auction and, if I can get the damn thing through an Ontario Safety Inspection, I’ll let TTAC’s very own Derek K drive it.

Therein lies the rub, or brake rub really. The front discs were rubbing, a lot. Constant grinding sound as the wheels turn. I have since removed/lubricated the caliper sliders (they were a bit stuck from sitting) and measured the discs and pads using a measuring tape and straight edge, everything is above min specs.

With the pin lube the grinding noise has abated somewhat but continues, worst is passenger side.

The discs don’t feel warped (no front shudder under hard braking).

Your thoughts?
