Technical car seems to have a dead spot

[Crom1]

Good evening from a newbie,
My Punto Grande is an 08 plate with 38000 on the clock seems to have a flat/dead spot when setting off in first gear.
Just as you set off and press the the accelerator the car seems to die for a brief second, its annoying because you push the accelerator down more and increase the revs to get over flat spot.
Any advice Please.

Thank you

Sorry - obvious questions:
1. What engine
2. When was it last serviced?

Hope the information is of help.

OK multiple places to start:
1. Check the pipes under the air box - they rot through
2. Check/replace the spark plugs - mine likes NGKs
3. Check the cables to the battery (at both ends) they rot/corrode
4. Clean the throttle body: https://www.fiatforum.com/punto-mk2-2b-guides/307670-remove-clean-throttle-body-1-2-8v.html

5. If you have a laptop get a copy of MES (https://www.multiecuscan.net/) and plug it in

Flat spot at take off ?

The ECU doesn't react fast enough to the air amount increase and the mixture goes lean, or the mixture is already lean… I'd check (for):

- leaks in piping/manifold
- throttle body
- MAP sensor

Do you feel like the engine kind of hesitates when re-accelerating after a slow down while Driving ?

BRs, Bernie
