Hi
My Linea 2008 with 137k km on clock, has jerky take off on cold starts, especially during summer and is less pronounced on cold weather or with preheated engine. It feels just as if someone was pumping on the gas pedal and it disappears shortly after changing to 2nd gear.
So far i've changed following:
So far no fault codes set, but obd data suggests that it has fuel trim issue with long term and short term trims variating between -100% to 100%. I believe that data to be incorrect though. Fuel consumption is quite normal, 6.5 - 7.0 l /100 km.
Some have suggested it to be a timing problem due to an incorrectly changed timing belt. Also, a burnt valve has been mentioned. I'd think these would cause more trouble.
So has anyone had similar issues with their GrandePunto or Bravo which are almost the same under the hood? How did you get it resolved?

So far i've changed following:
- spark plugs, spark plug wires, ignition coil pack
- both lambdas
- map sensor (which had faulty iat, and now has more power on lower gears)
