[clio carl]

[jesus]

That'll be your spark plugs, one of your HT leads or your coil pack.

 

[Paul RN]

Yep, sounds like a miss fire

 

[clio carl]

ok cheers guys i changed my spark plugs about 2 weeks ago engine sounds really noisy down to the shudder just to add i had 16 new valves timingbelt head skimmed done about 5/6 week ago due to pretensioner collapsing and i have now got a whine in first and second gear also when revs are dropping back it just seams really lumpy also i seem to have a buzz from my throttle body

buzz from throttle body may be the normal noise it makes. It does make a high pitched noise.

Is it lumpy and popping all the time or just while the choke is on?

If its any help mine does it with the choke on and is fine afterwards once warmed up

[Da]

J - He lives near me

Rich - hot or cold, doesn't seem to make a difference.

 

[OEM Battery Nonce]

Have you checked all the wiring? I know the garage that did mine said it was bad earth on the ECU and the ECU contacts, could be worth a try

 

[OEM Battery Nonce]

Just to add, do you have a Decat?

 

[BenStanley]

So many people so close lol, try the wires under the fusebox, they often corrode, and check the ECU connections etc, you checked the Lambda sensors?

were are you located mate is there any chance you can come and have a look for me as im crap at the whole car thing lol

 

[Ridahz]

My car will cut out sometimes when i start it if i dont give it a little rev, its not happened when warm though! Also in cold weather will give a pop or 2 from the exhaust. And finally i got the whine sound from 1st and 2nd gear at low speeds :rasp:

Sounds just like mine to be honest mate! But never gives any problems once on the road, i think most are like this matey but unsure. Just thought i'd mention that i have the same sort of things happening

It could well be a Lambda then, it it's not reading right it'll mess with the fuelling and could cause it to overfuel, giving bad performance and then the backfire, I live in foulridge, but am currently in Leeds for uni exams. When I'm back I'll give you a shout, I have a spare Lambda or can try mine to see if it sorts it

The car is still under warranty though so bear that in mind before you start messing with sensors etc.

Personally I'd have it back to Perrys and explain to them you're not happy. As I said to you yesterday, if it was my car I'd be dumping it back with them and not wanting it returned until it was 100%.

yeah true i dont know if my sensors are coverd under warranty tho or its wear ect im not going to even touch the sensors untill iv spoken to perrys to see what they say

 

[dobbo]

mine runs alittle lumpy ive been told many do
also i get popping from my exshaust always had but its always ran well enough

 

[OEM Battery Nonce]

Agh fair enough, if it's under warranty, steam into your dealer with a very stern look on your face and pick your target, tell them you want it fixing please, as it's not running, if you're polite yet serious they should sort you out swiftly and free
