My son has a Fiat Punto 1.2 (2000) MKII (I think) and is currently expeiencing some difficulties. He's taken it to a local garage and they have said that he needs to replace the ECU and it'll cost araound £400 - which I think is a bit steep.
His problem is that he'll be driving along quite happily and suddenly loses power. At this point the Injection System Failure light comes on. A couple of minutes later the light goes off and the power comes back.
I've just driven it back from the garage and it started, but there was a rattling coming from the engine bay (like thin pipes banging). Moving off, there was little power. Once driving I needed to keep my foot flat on the floor (engine didn't race) and took a few minutes to go through the gears and get to 40 mph.
After a another couple of minutes the there was a judder (the Injection System Failure light went off and came back on) then a few seconds later the light goes off and power is restored.
Excuse my ignorance but surely this is a fuel problem.
We also asked them to investigate a knocking from underneath the rear of the car and was told that it was the exhaust knocking due to the engine misfiring (it's been a while since I've had a misfire, but they were a bang/pop as opposed to a knock). Don't know if this is connected.
Anyway I'd really appreciate any insights and solutions to this that hopefully won't cost £400:bang:
Thanks
Tony
