Sajeev – you wanted questions, I have questions! First – I love your column. Great advice, and well written. Now my question(s).
- I have a 2009 Nissan Xterra 4wd, X model, 52k miles, and no problems except door squeaks and rubber molding which wont stay attached but that’s trivial. My question is, when should I have a “tuneup” done – i.e., change the spark plugs. Should I wait until Nissan’s recommended mileage (105k miles I think), or do it sooner? And should I replace all the coils at the same time (I presume the truck has a coil-on-plug ignition setup)? What else should I have done at the same time?
- Re: same vehicle: at 36k miles (May 2013) I did a transmission fluid dump and refill at local dealership, and did the same again at 49k miles in May 2014, again at dealership. My plan is to continue this dump and refill procedure every year for as long as I own the truck. Am I on the right track here? I’ve also had all other fluids replaced, except brake fluid which will be replaced when I have a brake job done.
Thanks for your advice, and keep up the good work.
We had two updates to a previous Piston Slap this weekend, surprisingly within two hours of each other. Let’s hear from the OP first:

Sajeev, reporting back:
You may be interested in this, if for no other reason than to add to your diagnostic toolbox; my experience certainly can’t be unique: Several comments below your post also suggested the motor mount(s) as the problem. I more recently discussed this with a professional wrench acquaintance, who also said that the mounts can be expected to go south after ~80K miles; he suggested using a padded floor jack to lift slightly on the engine during a time when I detected the “rough” idle (the oil pan on this vehicle, and maybe all Duratec engines, is waffled cast aluminum). Bingo! The vibration ceased when I did that. (Read More…)

Nice to see you are still at it on TTAC. (Back at it?)
So my story is a 2010 Audi A4, Quattro 2.0t Premium. Red, as it should be (No, it should be brown. Duh. – SM). Just turning 60k miles. The engine is an EA888 according to Wikipedia, twin chain driven counterbalance shafts as is known to work so well on I4s. Production commenced 2008 and its in all US A4 B8s with the 2.0 gas engine. Inside oil cap the gallery is clean as can be, I keep the VW spec Mobil 1 changed with my mityvac. New plugs, NGK of correct part number, air cleaner path is fine. The rest is original unmolested.
The issue is it runs rough. Slightly, as in the car does not shake but I feel it. Worst, dead cold, running at just above idle up a slight incline. A miss. Since 25k. Goes mostly away when warm or when power is asked for. No codes. Sort of feels like a tire flat spot but it did not go away with new tires. (Read More…)
I just wanted to follow up the post with the resolution. I’m not sure if this is important to you all, but I see that it’s an issue with Bimmers sometimes as well. I switched the bulbs from right to left. My passenger side light had been flickering off. When I switched the bulbs, the issue went to the driver’s side, which seemed to narrow down the issue to a bulb problem. (Read More…)

In the years since I last wrote to you my personal circumstances took a few turns. When the dust settled, I ended up with three cars. I decided to keep all three cars. The Cobalt is my daily/winter driver, and I will drive it to the ground. My wife loves the Mustang: we drop the top and take it on a cruise, she loves it, and it gets us out of the house.
About a year or so ago, I was feeling sorry for myself, traded the Impala in, and bought a new 2011 2SS Camaro with a six speed. It is a very cool car. If I’m having a bad day I pull it out of the garage, detail it and look at it. Once in a while, we may take it for a drive. Those drives are getting more and more rare. Less than 8000 kms on the clock, but I’m not planning on selling it. That may change, but not for a while… (Read More…)
I’m a long time lurker, first time asker. I was curious about the effects of E85/E90 ethanol laced gasoline. I have read a bunch about how older cars are susceptible to corrosion damage to various parts of the fuel line. (Read More…)

I can’t believe it’s been two years since I asked you to post a problem with my 1999 Subaru Legacy 2.5 GT. It may have been fixed with just a new gas cap.
