i have a 1.4 puma as a run about dropped on 17's and a green air filter, i have run the car like this for about a year and recently it has just lost power, it feels like im pulling away in second, it struggles top end and it just not vert revy.
i have had it on one of those comuter brain things? and there was no problems in the reading?
my dad has said about something in the air flow metre my need cleaning or replacing any ideas????

 

i think you dad is talking about MAF (mass airflow sensor) sensor located just after the airbox try cleaning the inside but dont touch the wire inside just clean the housing
