My wife drives a 10 year old 998cc Micra. A few weeks ago the engine was doing some frantic kangarooing when being driven. It didn't happen all the time,but was worrying enough for it to be taken to a garage.
It cost us dearly as it needed a new catalytic converter, a new lambda sensor, new HT leads, plugs, dizzy cap, air filter and rotor arm. The car ran very well for a few days except for a couple of hiccups, but as the fuel pump had started making strange noises and then packed-up altogether I put the hiccups down this.
I replaced the fuel pump with a fairly new looking one from a scrappy (saving about £140) and the car has been running beautifully since until a couple of days ago when the hiccupping started again. It feels as though the fuel has been briefly shut off. It clears; the car runs fine, but then it happens again. There is no pattern to this and it may be many miles between hiccups. The car has a 16v injected engine. I'm at a loss as to what to investigate next. Any ideas, please?
