Around desember, i was driving my car, when suddently the motorelectronics lamp started blinking. The engine started vibrating and there was little power.. After a while, the lamp dissapeared and the car started acting normal. But often when im driving now, i feel the car almost humps and coughs a little, when i try to just maintain the speed. But if i accelerate, it feels all good. No motorelectronics lamp after first time either. just wondering if its a sign that the airlow meter needs to be changed. Sparkplugs were changed right before i bought the car. Airfilter too.
