2008 accord 2.4 Slight pinging under light to moderate throttle #5214709 09/16/19 08:40 PM

I don't notice this problem frequently but it is typically in hot stop and go traffic. When accelerating on a quiet city street I can hear a slight rattle/ping/knock for a second or so before the trans shifts. I have heard it before but not recently.

I was driving today in some very hilly terrain with the car fully loaded with 5 adults. The car has some hill grade logic control of the trans where it will hold a lower gear if driving up a big incline if it thinks a higher gear won't be able to hold the speed. It will also drop down to a lower gear if it senses the speed increasing downhill despite brake usage.

Today I noticed a more than typical amount of this light pinging noise when I was accelerating up a decent incline under light throttle. When the engine speed got to a point where it would normally make this noise under light load ,and then shift, it held itself in that gear for like 10 seconds in the same light load situation and pinged away.

It did this until I gave it some throttle and revved to like 4k.
Last fill-up was at a random Loves truck stop in Ohio.

I typically use Costco fuel And I can't say I remember this noise in the last few months.

I'm thinking I need to run some techron,, has probably been 10-15k since I put any cleaner in there.
Or this was some perfect storm of events given the terrain and loading?

Costco gas is top tier and among the best.

Original 02 sensors?

Even tho they may not throw a code, they get lazy.

There are other things also.

I would start with, what is the maintenance history of the car? At 154k there are some things that should have been done by now that could effect what you're describing (new plugs, valve adjustment, etc)

Love's gas near was only 92 octane... Which surprised me because everywhere else it is 93. Just something to think about. .

I agree with ctechbob post.

So all this happened using that same tank of gas?? Me wonders if you got an "iffy" smirk tank of gas...….maybe let it run low, fill up again and see how she runs.

Car has 162k on it now.
I changed the plugs w new NGK and adjusted the valves myself at 105k.
O2 sensors are original.
It was about 80 degrees outside.
I didn't hear this noise at all on the 50 min drive back to the house.
Temp had dropped to like 60 by then.
Oil level is full. But this car does use about a quart every 1200 miles, especially doing 80 on the highway.

That's high oil consumption. You could add carbon build-up in the combustion chambers as a possible cause of the pinging.

The station are switching over to winter grade fuel in ohio. My 09 altima and impala are both pinging and will until they adjust to the fuel. I drove to St. Louis and never had an issue this last weekend with fuel from there, got back and filled up and it’s back.

My Nissan uses a little less than that and has since new yet still pings when winter blend hits the stations around here. I’m gonna run some kreen through it and hope for the best. My guess is Nissan had a bad tune on these engines trying to squeeze mpg out of them and I’m paying the price through oil consumption. It’s surely not from lack of service because I’ve changed the oil religiously every 3700 since new and usually used synthetic.
