Hi everyone
I own a Uno Mia 2003 model 1108cc, carburetted.
I have been battling to get my fuel consumption within acceptable range for months and have spent quite a bit of money. Averaging 350km on a full tank
I have:
replaced spark plugs
change air cleaner element
replaced entire distributor with new one from FIAT
had the carburettor overhauled by a carb specialist in Paarden Eiland, by a man named Danie.
Could an expert please answer the following questions that have been plaguing me for months now, and no mechanic can give me honest, technically sound answers.
1) Is the Uno temp supposed to remain with the needle in the middle of the gauge through all driving conditions?
2) At what temperature should the fan come on.
3) What is the purpose of the breather pipe that attaches to the air filter box close to the oil breather from the carburettor and what effect does it have on fuel economy and engine operation when blocked off? According to Danie, he just blocked it off in order to drop the idle revs, saying it does nothing...
4) Does the above mentioned work with a valve, is there a valve in the air box? According to Danie it has a valve that has failed, therefore he blocked it.
The new distributor has improved my ride by miles, but I'm still having fuel issues. I can smell fuel in the exhaust fumes, but Danie said its fine and one cannot get rid of the smell competely. Is this correct or is that not wasted fuel I'm smelling?
According to Danie the C02 percentage reading should be as low as possible indicating better fuel consumption, so to him 0.60 is better than 1.35 on the emissions meter. Is this correct?
Thanks for your patience and answers in advanced guys. I really appreciate it and need help. alexGS would love your input too as you seem to know a lot about these cars.
Thanks
