Re: Juddery throttle response...
Does it do it all the time or when the engine is just hot or cold ???
I see it's (outside) temp dependent. This to me would suggest a problem with the air temp sender if the 16v has such a thing.
Have you cleaned the injectors with injector cleaner ??? At low revs, the fuel pressure is gonna be lower so if they are blocked/clogged, you might notice it more. Also when the outside temp is colder, the car will try and push more fuel through, but the pressure is still gonna be low at low revs. Does it idle properly ????
