Replying to: masonjk (Oct 20, 2008 4:50 pm) Masonik,   I am sorry to hear that your car has pining noise and could not get it fixed. I believe that Honda car are generally good in quality (I used to have civic and accord) as most of people said here in this forum.   Maybe we are the few ones unlucky to get the cars with lots of issues.   After putting the engine injector cleaner and run different brand of gas for more than 5 weeks, the pinging noise in my car is gone. I am not sure if this is because of colder weather or gas quality. Where do you live?   I once called Acura at CA for my car's rattle noise issues, I got similar response from them saying that the car is designed to like that (sports car) and the rattle noise is normal.   Lesson learned is that test-driving a brand new car carefully even it is claimed high quality cars. 1% bad cars out of total is still considered to be good brand car (p-values < 0.01). We are the 1% ones. Replies to this message: masonjk (Oct 23, 2008 4:03 pm) charles12 (Nov 03, 2008 8:10 am) masonjk (Nov 11, 2008 6:20 pm)

Replying to: charles12 (Oct 23, 2008 11:16 am) I am on East coast in MD. They have put top engine cleaner in it and still pings. I run 93 octane all the time, and have used Exxon, Citgo, Shell, BP. not sure if they are the problem or not. I can't believe Acura would put such a finicky car on the road as to mandate 93 octane from one specific gas company must be used. Weather here now is in 50s during day and I can hear it ping with steady acceleration- usually begins to ping around 35 miles/hour up to 45-50. I plan to still go back to Acura. letter received from Acura today indicates they consider this to be normal. My response to that is so they consider engine pinging to be normal, and we know engine pinging causes performance issues, and potentially engine damage over time. Nice to know they consider this normal! Replies to this message: charles12 (Nov 03, 2008 8:10 am) masonjk (Nov 11, 2008 6:20 pm)

Charles   I have a 2007 TLS and it's as quiet as a mouse. Acura needs to replace your Lemon! Replies to this message: charles12 (Oct 24, 2008 5:47 am)

Replying to: gbosil (Oct 24, 2008 4:17 am) gbosil,   That is very kind of you. Since Acura consider it normal, I do not expect them to do anything. I tried to put rubbers between the windshield and dashboard, it works for some noise. But I do not know how to fix those from doors and back near the windshield. There is a gap about 1/4 inch wide between the door handle panel and the door body on the passager side, from the gap I can see the inside and the wires there (poor assembly quailty). Rattle noise comes from the door (at least 2 locations there).    1 out of 10 times (from home to work 20 miles each way) the car has no noise.   Charles

Replying to: masonjk (Oct 23, 2008 4:03 pm) Masonik,   Just want to follow up to see what they did for your car.   I most recently noticed abnormal engine sound + almost unnoticable pinging noise when I accelarated the car . I used Mobile gas for the last 2 tanks (I was told by Luxus dealer, when I do my maintaince for my 2007 RX350 there, that Mobile gas contains up to 10% ethnol. Suggest using NOCO or Quickfill Gas).   Do you think that any computer program problem causes the pinging? Replies to this message: masonjk (Nov 11, 2008 6:20 pm)

Replying to: charles12 (Nov 03, 2008 8:10 am) nothing done yet- have been traveling a lot and have not had a chance to get car back into acura. Hoping to later this week before doing road trip next week for 600+ miles. Still pings...typically during steady (but not hard) acceleration at speed between 30-50 mph. I hear it happen when engine is cold and also after it is warmed up.

Replying to: habitat1 (Aug 13, 2006 11:11 am) This is exhausting reading ..... all this misinformation. I worked for both Chrysler and GM and have a mech. eng. degree (no big deal). Premium gas is marketing genius at its best. The oil execs luv all you premium gas buyers. They have pulled off the biggest scam on the public and have made billions, simply by using the word premium. "Premium" means "the best". WRONG. Unless your going to attach a 30' travel trailer to your BMW, Mercedes or your Chevy pickup and pull it uphill to Tahoe - You are absolutely wasting your money on premium. In fact, at Tahoe's elevation your premium will fail to burn 100%and cost you about 25% drop in efficency. I have never burned anything but the cheap stuff in my cars, except my '67 Rover 2000 which had a compression ratio 15:1 (after I got done with the rebuild). You burn premium in a Yamaha and Suzuki motorcycle that redlines at 11,000. Not in a car that redlines at 4500. Your compression ratio will dictate what you burn.

Replying to: geojb3 (Feb 02, 2009 2:28 pm) I am geting a 2006 Acur TL and the car has a 11.0:1 compression ratio and it is recommended to put 91 octane gas. Would you suugest that a lower octane will work just as well as the higher octane.   Lower octane will not burn at the correct temperature and might ruin the sensors and engine. That is what I have read.   Just a question.
