Hi there.
I'm new to this forum and hoping to find answers to my Fiat's bug.
I drive a 2000 model Palio 1.2 mpi (8Valve) fuel injection, with 196000 km on the clock. Bought 1 year ago.
She runs fine 90% of the time, but has this mind boggling issue... please bear with me as I try to explain.
I drive 84 kilos to work and back every day. Being a shift worker I would drive in the mornings, afternoons and at night, the same journey. She would have no trouble except on a hot summers afternoon (like over 30 degrees).
About 20 kilos or so into the journey the car starts to loose power, and sort of "floods" if I press the petrol pedal. She would start and idle fine, but if you try to rev her, she smothers and cuts out.
In order to keep traveling, I have to be very light on the petrol pedal, stay in first gear until she eventually picks up enough speed and revs to change to second gear. If you dare press the pedal a bit more she stalls, but starts again and idle fine.
Please note that this ONLY occurs on a hot day, never once in winter, (although last summer I had a view of these issues, then winter came), never on a cool, rainy or cloudy afternoon and also never at night.
The car's temperature gage does not climb during these "episodes", and no lights in the dash comes on to warn of anything.
What I have done thus far: No 2 piston had no compression so I had the valves done, only to discover that the no 2 piston had a broken compression ring. We therefore put new rings, bearings etc.
I took her for a Diagnostic test and a fuel pump pressure test, after the tech cleared some minor stored problems, nothing showed on the diagnostic and the fuel pressure seemed fine.
I have changed plugs and bought a set of new plug wires, (replaced the lot), and even replaced the battery (was just old but still good).
Can anyone advise me where I can start to search for this problem? I don't know much about cars but the mechanics in my area is guessing just as hard as me. We don't have a Fiat agent nearby, only in the city. So any help will be greatly appreciated.
Other than that she's a great little car, light on fuel and still very willing to run. She was well looked after by her previous owners and I'm planning on posting a 200 000 kilo pic of her soon.
Thanks
