1.2 with 55 kw: vehicle is not picking up any more gas at the moment

Moinsen, the car makes me despair. The following situation: Irregularly the vehicle no longer accepts gas, jerks and as soon as you take your foot off the gas and latch on it again everything is normal again. What I tried so far: New spark plugs, the old looked ok for me. Coolant sensor replaced sensor for suction tube pressure replaced air filter renewed camshaft sensor already before replaced ignition coil 2 years ago (not sure if the ignition cables there also getausc The error memory is empty, yesterday the test drive showed P0130 for a short time, but did not occur again. Do you have any ideas what else it might be?
