From new my Palio Go has been giving me this problem. I have been to more than two Fiat dealers and to be quite frank they are b... useless. The car cannot iddle consistently and then from time to time it jumps to high revs (no RCC so don't know how high but its pretty screamy). They replaced the sensor that adjusts the mixture based on the output in the exhaust (they first took it out without telling me and the fuel consumption went through the roof!!) but that did nothing. Then they kept pretending like they couldn't hear anything wrong. Then they kept telling me that it was running to spec. Well is all horse sh... - any new car should not run like this thing. So now its on 23000km and still no sign of FIAT actually caring about getting to the bottom of this (which just makes me more suspicious)

Does anyone else have this problem and if so did you get a solution?

Cheers
Owen

hi there,what engine is fitted to your palio?

your engine is petrol or diesel?

I had the same problem with my Palio 1.2, but it recently stopped on it's own.
I've just reacjed 28 000 km and I've had the car for 2 years already.

But a new problem has shown it's head.

I't seems I now have a Electrical problem with the car, and Fiat says it's not under warrenty, as the electrical warrenty is only 1 yr on anew car.

I don't know for new cars, but on the old-ones IDLE regulator was the problem. Look at it, if the RPM jumps high and your car has that regulator, it's 80% probability false regulator. If your car is DIESEL, then ignore this post.

hi I have a 1.2L palio petrol in India. done 21000kms. 1 and half year old.

i have the same problem the revs shoot about 400 to 500 rpms more than my accelerator lnput. it happens only for 1 to 2 kms after a cold start. on pressing the clutch, the revs shoot up to 1500 revs( normal 850-950 revs).
It automatically stops after the engine temperature increases.

please help.. as the car accelerates without me pressing the throttle....

I´ve not experimented that problem on my fiat 1.6 16v , but on another car (vw golf) this problem often is corrected realigning timing belts, due actions as sudden accelerate or worn belt, is enough to skip one tooth to change the correct firing order at least in one cylinder; try to find the witness marks that match with the TDC (top dead centre) on cylinder number one (prior to detach belt), generally crankshaft and camshaft pulleys are marked to match with the block or head reference. Be careful and good luck.

Hey man, this is not problem, this is very old technology to help you with cold starts, it's name is automatic saturator! hehe
Serious, if your engine is cold, saturator is activated and he is upping revs like you said about 500rpms till your engine has adequate temperature (after 1 to 2 kms usualy)
It's because engine can stops on usual revs (about 900) in the case he is cold...
Don't remember from old cars? For example Fiat Uno had little handle and u had must to pull it before cold start and this manual saturator increased revs ; after few mins u push it back and revs came to normal value; this is the same case but satruator is now automatic...

Hi i had the same problem, but couldn't get a resolve, then my waterpump went and had to have it replaced, i thought i would do it on my own with my father in laws help. I thought well seeing as the watercoller cam with a cambelt might as well change that and the fanbelt, i know it probably wasn't needed but after that it stopped, i think it might have had something to do with timing or belt alignment or something. I am also from South Africa and have had no luck from fiat guys, either no stock or cant fix it themselves. I now have had to use a bicycle brake cable modified as an accelerator cable, needed to remove the thermostat altogether because new ones were not working. But i do love my car.
