Hello everyone, I have a cadet with 1.4 engine 44KW. (C14nz) When I start it, whether warm or cold it just twitches around and has no power. It is practically not mobile. I have read out the fault memory and it spat out error 44 (lambda probe reports mixture too thin)! I have already renewed or changed many things to the test. UA: new candles, new ignition cables, new zunds coil with new ignition module. I checked all cables and plug-in cone, the distributor sammt Fin now my question is what can it be now? I am grateful about every helpful tip. MfG Kaisi
