I would re check everything was put back correctly before moving onwards.

poor performance is classic timing issue

Re: 1.2 consuming too much fuel

Non safe engines will run fine with the cam belt/chain/gears one tooth out of step. It;s well worth checking. The RHS wheel arch liner and inner cover have to be removed to see the end of the engine. You cannot get to all screws on the smaller cover. The only way is wheel arch out of the way.

If timing is out, it should also misfire ? But it is not, fuel consumption is very bad around 10.5litres/100 km

No If camshaft timing incorrect by a small amount it will not cause a misfire

Re: 1.2 consuming too much fuel

Hi Chali

Yes its looking like a good thorough check on the cam timing would be my focus.

you shouldn't need do be buying any parts to do this so its a freebie just a bit of time.

Re: 1.2 consuming too much fuel

So i adjusted timing again, put new spark plugs, new thermostat valve, interchanged 02 sensors and checked brakes as well. After sparks plugs the consumption decreased, but still it is giving 8.5l/100 km (26.7 mpg )
What could be cause, i did compression test also, all cylinders are between 210psi to 220 psi , which means engine is ok.
I am fed up with this tiny 1.2 litre 60bhp engine which is consuming like 200 bhp

Hi,

Remove the valve cover.

Set engine to top dead centre cylinder 1.

Post photos of the camshaft lobes of number1 cylinder and number 4 cylinder.

Re: 1.2 consuming too much fuel

What is your daily driving like, are you driving 10 miles down the road on every trip at a steady 80kph or are you sat in bumper to bumper traffic on the morning commute creeping a few metres at a time and burning a tank load of fuel while hardly moving ?

Did these problems exists from when you bought the car or are they something that has developed while you’ve owned it ?

should drive fine, my 1.1 and 12 do. Take it for a drive.

Need to know if the mpg goes up or down

and does the acceleration improve

We have to start eliminating possible problems. Otherwise we will be here for another three pages of suggestions. Unless you post some pictures of the live data from the sensors

City mix driving, even that should not give me 220 miles for a full tank of petrol. Acceleration feels underpowered if compared to other pandas, engine is also louder than other pandas. I had 3 pandas , thats why i can relate.

So it looks like you have gone over every possibility of what could or couldn’t be wrong with it before in this thread here https://www.fiatforum.com/panda/4808...tion-ok-6.html

You probably should have carried on that thread rather than starting a fresh because people are just suggesting the same stuff again....

If you’re getting 26 - 29 mpg on an older car driving in city driving short distances, which is what your other thread says then it could easily be there is nothing wrong with the car.
