Guys....
I need your opinion.
I get slight engine knock on my 2000 TL. Odometer reading is at 116000. I've had all services done and change oil religiously. Gasoline used is at least 91.
I can hear detonation at certain speeds when transmission is in the higher gear and I rapidly press accelerator pedal. It is not that loud but still pissing me off - I want my Acura to run smooth
There is no check engine light - proof for the sensors to be fine. I guess I cannot claim my extended warranty with Acura - they need to see the light first to run diagnostics.

Anyone knows what it might be? Is it a valve clearance need to be looked at? ...Damn...only 116000 km.

Any responces are appreciated.

 

have you checked the spark plugs?

 

Get some fuel injector cleaner like Techron.

 

I put in brand new Bosch 4+ just a couple of months ago

 

Do you think injectors are plugged?

 

those arent any good for our cars!!! get the NGK iridiums. 2nd are you sure its detonation? get a fuel treatment(fuel injector cleaner) run that thru acouple tanks. but first get rid of those plugs

 

Tru theres this Injector/fuel sys treatment at EvERY pump station that you add to every tank...do it 1nce every 6months.

Like FSTTYS1 said, those sparks you put are a no no, get NKG iridiums and Oh...THE MANUAL SAYS 93OCTANE UNLEADED...91 sometimes is acceptable...but "atleast 91" is not acceptable.

 

those plugs are shit. They might be running to hot. Like everybody is saying, go back to using the ngk's and drop in some injectors/fuel treatment.

 

Thanks guys...I'll try to switch the plugs. Funny...the reason I got them in the first place is because I read some good responces from this board....go figure
