My 2006 GP 1.4 16v Sporting had a standard service 2 weeks ago (filters, plugs etc. all changed). I decided to put an aftermarket air filter on the car the next day and all was running fine.
A few days ago my car started cutting out when I stopped at lights or in traffic (not all the time, just now and then). Every time I stop though it sounds as though it is struggling for air and the revs go up and down. Today it has started making a whistling/hissing noise from the engine bay but when I accelerate the noise goes. Anyway I decided to put the original air box back on the car and it has made no difference! My car still sounds as though I have the other air filter on it too when I rev! Any help would be much appreciated!
