got bad engine symptoms on my micra 1.0 k11, it suddenly stopped tickin over an runnin rich afta i put some injector cleaner in fuel day b4,an5 mins afta i sprayed maintanace spray into air inlet. It would stil pull ok through revs,though it was a bit splutery.It kept these symptoms for 2days,then one mornin it started up an ticked over fine but put foot down an it starts2 wanna die at about 3000 rpm i guess,just like fuel starvation.So its suddenly got these totally new symptoms now. Its pumpin fuel through filter fast,how much pressure does it need?is there an easy way 2 find out?could it be the sensor nakerd that tells position ov butterfly? the more you put ur foot down the worse it gets,it sounds like a rev limiter 2 listen to,obviously it aint. does that sound familiar? really need2fix it cus need it 2drive this week,failiar aint an option an very limited funds,would really appreciate the help anyone thanks...
