50 Km/h, 2,000 RPM stumbling

[Fenian]

Hi

I posted another thread on blowing fuses. Here's my second issue....

When accelerating in third gear or fourth gear I get a stumble in the engine, almost like the car isn't getting the fuel it needs, at around 2,000 RPM / 50 KM/h.

I've had the fuel filter changed twice (not the issue) and it has been serviced (non Seat garage) in the last year....

Any ideas?

engine type would be useful...

Ahhh yes...

1.6 SXE

Any ideas?

 

[coolypops]

does it only happen around 2000rpm or is it at higher revs aswel?

It usually only happens at around 2,000 RPM and 50 Km/h.

not 100% up to speed with this engine but sounds like a fueling issue...

I know this might sound stupid but is your air filter semi-blocked?

Worse case scenario it could be a head gasket going. My cordoba did this when the water was getting into the cylinders.

However could also be, Lambda sensor, spark plugs, coil, CAT, fuel pump and air filter.
