Fellow tsikoteers I want to seek you opinion because I am experiencing very low fuel consuption on my vq30 cefiro. I am only acheiving 3.8 km/l on alabang bf route. I sometime also encounter times when my car wouldnt rev up past 2k rpm then stalls, sometimes on slex it just cuts out without any warning. No check engine light is on but i think its one of the sensors. What can be the sensors that may lead to these symptoms. TIA
