Technical Tipo 1.4 ie

[snobbler]

Hi Everybody ,

Newbie here on the Fiat forums , so please be gentle

My wife has got a 1993 tipo 1.4 ie , looks like a wreck but goes really well .
However , recently it has developed a flat spot around 3000 rpm , which seems to be getting worse and is now "hesitating" on the flat .

I have changed the distributor cap , fitted new plugs and leads , checked all the connectors for corrosion etc but still the same problem.

I was going to overhaul the carburettor , but have just discovered it has a bosch mono jetronic injection system instead ( well , it looked like a carb)

The manual I have got only covers the tipo models with a carburettor- and I can't find any information about the 1.4 ie .

Does anybody know if a manual for this car is available ? It seems to differ in many ways to the standard 1.4 tipo . In fact , there is a box thing mounted in front of the offside front wheel with a blue pipe going to it which I have no idea what it is - the pipe goes back to the fuel tank so I am guessing it is a breather of some kind ????????

If anybody can help with info about a manual - or what on earth the box is- please let me know .

Many thanks

changed filters? fuel and air ones. once those are changed fill the tank with injector cleaner. redex or whatever its called. and take it out for a good italian tune up!

that should sort it out hopefully.

Thanks for the reply.

Yes , the air filter has been replaced but I only found the fuel filter yesterday under a plastic plate by the offside rear wheel so that will be replaced next.

so you have a 1st gen fuel injection?

if a fresh filter and thrashing doesn't solve the problem, it may have a worn out throttle potentiometer.. expencive new so I'd thieve one off a scrapyard car if you can track one down.

www.porterpublishing.com Do a manual for your car, it's the same as mine see. Get the Tipo/Tempra manual. Happy days, good luck.

Hellcat, is a potentiometer, a posh name for a variable resistor? hehehe

You can also check the black rubber pipe between the inlet manifold and Digiplex. When it leaks, the advance and mixture go wrong, which is noticeable especially when driving with low rpm (e.g. 40 - 50 km/h with 5th gear engaged).
