So... I purchased a used 16 ILX Base w/14k miles. I came from having a 12 Lexus ES 350. Is it normal to be able to feel the idle of the drivetrain? Such as when is 80 degrees outside and I leave work, I sit at a couple of lights and I can feel the steering wheel shake ever so slightly at the tune of the idle. The ES350 never had this issue so maybe it's just the difference in compression ratio's or something I'm not used to.

 

I bought mine brand new, I have 18,000 miles now and starting to notice some vibration at idle and when putting in reverse. symptoms are intermittent though. I'm just going to let it go until my car dies then I'll take it in for warranty service haha..nah jk, I'd get it checked out.

 

4 cylinder compared to 6 idles a little rougher, especially with A/C on.

 

What kind of gas are you using? Top Tier only? Maybe try a bottle of gas treatment?

 

Just take it in for check up if you have warranty.

 

In all honesty I think that you were just used to your Lexus being a more quiet and smoother ride. I just got my ILX in December and I find it to be louder and shakier than my previous vehicle which was an '07 IS250.

 

Yeah... I had it checked by dealer before and they didn't think anything of it. Plus it is intermittent. It very well could be I was used to the V6 vs 4. There's gonna be some differences between Lexus and Acura as well. I've used multiple fuel treatments and premium fuel from Chevron since I bought it (used, 3k miles ago now)

My other question is if there's an EFI service like throttle body cleaning that Acura does at the dealer? I cleaned my Lexus throttle body after many miles and it made a big diff. I checked the throttle body on this one and don't want to mess with it haha.
