99 1.0 Engine Hesitation - garretta86
I have taken a look at the previous posts about engine hesitation and i seem to think mine is slightly different,

Im certainly not a car expert and im trying to figure out what is causing the following problem.

When my car is damp (not cold as when we had the snow it ran fine strangely!) or hasnt been run for a day the car starts to hesitate when accelarating. After the car is run though it works fine until the car sits for maybe a day without being used at which it hesitates again, i have had a load of issues with this car already and ive done a bit of research but dont have any conclusive answers.

Can anyone help?

Through research it could possibly be apparently, the idling module,throttle control or the fuel pump...

It happend when coming down the sliproad the other day so was quite interesting to say the least!

Try spraying the plug leads with WD40..

Sounds like damp affecting the HT leads... may need to be replaced..

If WD40 does make a difference, it will only be temporary so new leads will be needed.

If it makes no difference, chances are it's not them.

(But it's cheap and easy).

Also check the top of the resin from which the leads come - if it is covered with dirt you could get tracking in the damp.
Clean with dry kitchen roll.

If that makes no difference, we'll think of something else.
When were the spark plugs replaced?

Hi Madf,

Just to let you know i think the leads are pretty new as are the plugs, didnt find much dirt or signs of damp or even wear around them.

do you have any other ideas?

cheers!
