Hello all, engine 2.0 xsi petrol/gas 100kw.

When 2000 rpm's are reached, the engine begins to lag (choke), but when i give more rpm's it's all good. Same happens while on petrol and on gas.
Replaced the spark plugs, didn't help. Could this be the faulty spark plug wires or maybe airflow sensor ? Already had the car connected to diagnostics, shows nothing.
By the way, lambda's are working.

Thanks for any suggestions.:thumb:

Not trying to be clever but when you say "when rpm reaches 2000rpm it lags but if I give it more throttle" etc maybe the throttle position you are setting is the 2000rpm point! If you sit and rev the engine from idle to max, whilst out of gear, at a even pedal movement does the engine hesitate at all or climbs to the max OK?

Hello,

While out of gear and rev'ing to the max it doesn't hesitate.
