As of late injector light comes on and I have an instant power loss, only lasts a second or so, but seems to get beter when accelarating, it is getting worse and more frequent but still intermittent, any ideas ???
It won't be the injectors, but some sensor fault I would say. My wifes old Cinquecento used to do that. Then it started to idle really badly. I think the air flow sensor was changed after a Fiat diagnosis of fault codes. It cost about £100 in total to fix.
My 2.0 16 valve had this problem. It turned out to be an air leak on one of the four rubber pipes that join the 2 parts of the manifold together leaking air (the lip on the old one had been turned over when it was fitted). The part is dirt cheap but requires most of the inlet to be dismantled. She now runs much better.
