Hi, I have a 2004 fiat punto 1.2 8v active and I have been trying to cure the the bumpy, unsmooth rides. I have changed a buggeres gearbox mount, clean throttle body, replaced spark plugs and ht leads all of which have made slight difference, however it is still jumpy especially at low revs and unsmooth. I am going to try putting injector cleaner in next, what else could this be??? My last oil change was over a year ago, should this be next and is it easy to change the fuel filter?
Help!!
