Hi guys,

Another question for you all.

On tickover, I have noticed that the engine hesitates, has a hick-up but this is not evident whilst driving. (sounds like 'hunting' but not continuous)
I've changed the plugs and the fault is still there and my next test will be to change my fuel. I have heard that the fuel supplied by Tesco is not up to scratch, which is in the tank at the mo. Anyone else found this symptom :roll:

I hope it's nothing to do with the DI

Would a fuel filter change help?

Cheers,

Phil.

Phil try cleaning the throttle boy with some carb cleaner

Thanks Chris,

Will it have to be removed to clean it out?

Phil, just take the delivery pipe off and spray down the hole. Nice quick job

Finn,

Doesn't putting engine cleaner in the fuel do the same thing as spraying cleaner in the throttle body??

No, fuel enters the engine via the injectors, air enters via the throttle body. If the throttle bottle gets gummed up with particulates it can cause the rough idle, the carb cleaner just gets rid of this gunk and hopefully restores the correct idle.

Ok. Used 1/4 can of injection/air intake spray cleaner and sure, it has cleaned all the insides.

The erratic idle seems only to occur when the aircon compressor is in action and seems to want to stall, once/twice a minute. With the air con off, all seems fine. I know the compressor takes quite a bit of power from the engine but thought it shouldn't cause this hick-up.

A bit off putting when I'm at the lights. Switch of air con or hover over the auto gear shift and get ready for a re start

Phil I have the same problem at the moment with the acc compressor causing the car to stumble and has caused a stall:evil:

If your car is standard an ECU software reflash might help, from your dealer. Additionally it could be a acc compressor clutch problem, mine is being swapped out under warranty to see if that helps?

Annoyin though innit:evil:

 

[euroswill]

Yes it is Chris. Especially when next to an idiot in an Audi or BMW;oops: I'll get it looked at when next in for a service in 2k miles.

Thanks a bunch to all.

Cheers, Phil.

Yep, and with an auto you cant exactly drop the clutch and restart on the roll either :roll:

Where did you get the carb/throttle cleaner from by the way?

On tickover,

Ummm...what is "tickover"?

Tickover = Idle

I got it from my local car spares shop. It's called 'Wynn's Fuel Injection Intake & Carb Cleaner' Methanol based and by god, it really cleans the intake out. I had to put mu sun glasses on after Cost was about £4.50 but worth every penny, even if it did not cure the problem.

Thanks Phil

Why don't you bloody Englishmen speak English! :lol:

Or maybe it's us crazy Yanks that aren't speaking English?!?!

So to clean out the throttle body, just take off the intake pipe and spray it in??

Yep, I would suggest using a lint free cloth and cleaning off the excess as you go, you can also spray some in while she runs(she wont like it though).

Make sure the pipe is put on nice and securely afterwards

A quick note as well guys. I had to replace the large 'O' ring around the air intake which seals the delivery pipe to the throttle body. Perrished like a tarts gussett

Has that helped with the problem Phil?

Hi Chris,

No. It is still spluttering in the heat with the aircon on. Now I switch to 'econ' when at the lights
