Jazz Pinging

[fundies]

Ive got an 05 vtis cvt (25,000km's), and I've noticed "pinging" from the engine a few times lately when driving under load up moderate hills etc. You have to turn the stereo off and listen well, but its definitely the motor having a good ping. Im only using regular unleaded, but don't feel the Jazz should be pinging on regular unleaded seeing that its recommended. Anyone else notice this?:confused:

To really diagnose, try putting 1/2 a tank of 95 RON or 98 RON and see if the pinging stops. If it does, then it is the fault of the petrol that you put in, it could have been bad fuel.

[fundies]

It gets driven normaly, not like a granny. I often give it a good rev in paddle shift mode. With only 25k, it shouldn't have carbonised combustion chambers. Its not a bad batch of fuel either, as I've noticed it over a period of months (you have to listen real carefully, but it's there), I always use shell fuel (not the no name brand fuel). It gets fuel injector cleaner regularly as well. It sucks. I reckon all Jazz owners should turn down the stereo, head for a decent hill or incline, and have a good listen. May have to go to high octane:(

[aaronng]

Try Caltex and see if it helps.

[JasonGilholme]

stop using injector cleaner all the time and only use 98 ron petrol.

it'll be cleaner and safer and your injectors will be fine.

[KummaZ]

You say Honda recommend the Jazz runs on regular ULP. Its probably not recommended that you drive your car up hills under moderate/full load..

If you want to drive with regular ULP you should drive it like a regular grandma ;)

Edit: And for the little difference in price why would you bother running regular?

[STOCK]

thats pretty worrying, doesnt the jazz have a knock sensor to knock back timimg for lower grade fuel?

[fundies]

Definitely not injector sound. I know the difference between the clicking sound of injectors and the metallic "crackling" sound of an engine that's pinging. Anyway, I'll try higher octane fuel as a personal experiment, but I think that it could be a problem with Jazz's, but people may not have a good ear mechanically to pick up on the problem. Either way, if I can't eliminate the pinging then I'll eliminate the Jazz on the second hand car market.

[JasonGilholme]

stop using injector cleaner as well.

its probably reudcing the octane level of the petrol. your injecters shouldn't need to be cleaned "regularly" especially when its under 100,000 k's.

[IZY-10]

use 95rom or adjust your timming

[JasonGilholme]

you also shouldn't need to do it to a jazz that is new and standard. problems like that should be sorted from factory.

[IZY-10]

No way on a standard Jazz to "adjust the timing".

lol my bad i am use to b series with timing belt

[Syd0rxl]

i got 07 vti jazz, so far so good. it just hit 1000ks today. i use BP Ultimate, it gives better engine response and fuel consumptions.

[fundies]

Just tried a tank of BP Ultimate. Guess what, no more pinging. Looks as if a few extra dollars a tank is the way to go.

[lionhart87]

i find that with BP ultimate i get more mileage compared to Mobil 8000.
Atleast 50km with the exact same conditions

good on ya..:thumbsup:

Do you think you could record the noise/sound and post it up?

[fundies]

No way, it's only a faint distant sound coming from the engine bay when driven under a load (e.g under light to moderate throttle uphill). Once you hear an engine that pings though, you never mistake the sound again.


P.S. The BP ultimate definitely gives the Jazz a bit more oomph. Very noticeable, and much more responsive on light throttle openings.

Don't use injector cleaners. They lower octane rating by a lot like what JasonGilholme said.

The only proper injector cleaning is ultrasonic cleaning, dumping injector cleaner into the tank is pointless....

"Just tried a tank of BP Ultimate. Guess what, no more pinging. Looks as if a few extra dollars a tank is the way to go."

Yup. Not many folks actually realise that Australian regular ULP is complete rubbish. I tell EVERYONE to use 95ron (and above) and to only use the major chain fuels.

I've seen too many independent stations getting sprung putting crap in their ULP to increase the margins.

[fundies]

I just tried a tank of E10 shell fuel, and I'm very impressed with the performance of this in the jazz as well. It pinged its head off for the first 20km's or so when switching from BP ultimate, but I'm sure this is just the ecu adjusting to the different fuel. I get good smooth ping free acceleration now, and a very smooth idle. Give it a go. Oh, and it was 2 cents a litre cheaper than regular unleaded.

Hi,
I also have a 07 Jazz with 15,000kms. I have noticed pinging a couple of months ago and each time i take it to the dealership, i can never replicate the problem.However i have noticed that on hot days the problem is worse to the point i am worried to accelerate hard.
Some suggestions are to use PULP. Why should that be the case though. Shouldn't the engine be able to cope?

[condomsakti]

smhee1, it could be CVT problem mate. mine also did the same.

[smhee1]

Condo,
Mine is a Gli 1.3 with manual tranny. So definitely not the CVT. Any ideas?

[smhee1]

Claymore,
To be honest i have not driven the car 'hard' yet. It does not mean i drive 'slow'. The average rev i use is 3 grand.

Regarding the gear changes, i am sure i am ok with that. I usually change gears at around 2.5 to 3 on the tacho. The pinging usually happens the moment i cluctch out and accelerate.

It also does it say when i am on the freeway hovering at around 100.

Definitely more obvious on hot days. Sometimes i could be on 3 rd gear, lift up on teh gas and the moment i press on the gas again, that moment it pings...

Does that give you any more thoughts

[smhee1]

Claymore,
Yeah it is I-DSI.

It also turns out that 90% going back and forth from work is on a 60km/hr road (around 1.5grand on the tacho i think), almost 500kms per week.

[smhee1]

Claymore,
Thank you very much. Yes this is my plan. Actually waiting for a hot day. We we expecting mid 30's in the last couple of days and got very 'excited' in the sense i was sure then i would be able to replicate the problem easily at the dealer, but the hot days never happened. This week should give it a go.

[siir]

or u caould try nulon total fuel clearner.. and use bp ultimate for 1-2weeks just to let the car settledown on fuel... it works on all my mates auto & manual..
hope that helps :)

[smhee1]

I finally managed to take my pinging Jazz to the dealership on a hot day. And they confirmed the pinging. Howver they could not put it down to any particular reason. They have asked me to run some PULP ( from MObil) and straight away the pinging stopped.
I am not sure now what the next step will be. Will call the dealership tomorrow.
I don't want to use PULP all the time as the reason i bought the JAzz was fuel consumption with Regular unleaded.
I will keep you posted

Hey mate:

You hear anything from the dealer yet? I have similar issue with my wife's Jazz, but no time to bring it back to the offical dealer, but I am pertty sure they can't (or won't) do anything anyway.
I try to fill PULP the other day, pinging seems gone, but still can hear couple of times and getting less and less. I bet the computer needs to adjust time by time and finally all disappear, therefore the pinging getting less & less. I applied this rule from subaru's car which known it from my friend (he is subaru mechanic).
What do you think? true or not?

[smhee1]

Yakuza,
Sorry being away for a while. It has been cold the last few months and the pinging has gone away, for now anyway. So mine is related to the heat. My dealership in trying to be proactive has decided to change my oxygen sensor. So we'll see what happens

[tedh1951]

I use 95 or better in my GD3 and don't have the problem - I experienced this with my '91 Civic and the switch from ULP to 95 or 98 worked a treat on that little beast too.
