Here goes I have a 2008 leon 1.6s when its cold its hard start some times when its starts the revs drop very low and once they pick the are still very jumpy i brought it to a seat dealer they put it on the computer and they say that it gave no faults?? but they replaced the temp sender any way it has got worse!!!! Has any one got any ideas what it might be ? thanks

Old spark plugs?

Faulty coil pack?

Faulty MAF sensor?

+1 for MAF sensor, it can be in trouble long before it registers faults.
