Just got an issue with my petrol auto 2.4; it appears to stutter at low speeds at around 20 to 30mph, and soon clears fine, but wondering what could be causing the issue?
I guess you discovered that by contacting the places that supposedly did the service ....if there are false stamps in the book then might be worth doing/getting all the alleged service work done againAccordaz said:I found out through investigations that my Service book has 2 recent false Service stamps in it!
I meant the additives put in by the fuel retailer.Accordaz said:not really thought about it until this happened, but due a fill up this weekend, so we'll see what happens; I don't put any additive in personally, only Tesco's improved mix!
The additives are already in the fuel when it comes out of the pump... all fuel retailers have to add it.Accordaz said:thanks for the replies!
You're right, Brian, it's now on my big list to get done next.
Jon, I don't always use the retailer additives due to the extra expense, but if there's an offer, I'll go for it; is there a company that has the best additive mixture?
I'm talking about ALL fuels, including Tesco Momentum 99!Accordaz said:ah, I'm talking about the improved fuels such as Tesco Momentum 99, Jon!
I'm fairly sure it does. I always use 95 RON, but there are others who use 99 RON and say that it gives more power. AFAIK this is true of all modern performance engines, the ECU uses the knock sensor to adjust the ignition timing.Jon_G said:I'm not sure that the Accord ECU allows the timing to advance and take advantage of higher octane fuels?
I know, but I'm fairly sure (from comments made by K20 tuners on Civinfo) that the standard Honda ECU mapping does not allow the timing to advance beyond the limits set for the recommended 95 RON fuel... logically, why would it? Same problem on our MR2, meaning that use of 99 RON is merely wasteful.freddofrog said:I'm fairly sure it does.

But maybe the K24 Accord has an ECU map that will take advantage of higher octane fuel?

was the other post talking about glow plugs ?Accordaz said:well, had my auto gearbox oil changed, and engine oil (Castrol 10W/40) at my local Honda dealer = £140 inc, and it hasn't solved the shuddering issue; so I guess we'll have to look into the plugs now to see if one of them is playing up; from reading another post, they're quite tricky to change, am I correct?
like Aspirin, price depends where you buy them :lol:Accordaz said:thanks for your replies; yes, they do look very different to the ones I used to take out years ago; can imagine they're expensive to replace?
