i have a Punto GT in M reg and the injector light is constantly on. the car judders at low revs and sometimes stalls. can any one shed any light on this matter. cheers Phil

You'll have to take it to a Fiat dealer and get them to plug it into their diagnostic - no point taking it anywhere else as they do not have the right diagnostic jack.

Probably a sensor gone somewhere - not point guessing, let them tell you.

Cheers.

Fiat will charge about £75 for it though.

Fault coming from 7 sensors, i done diagnostic las weak.... They recomend me clean all air hoses but i can see difference.....

So are you saying 7 sensor's are showing a fault??

I had something similar on our GT and it turned out to be the air flow meter. This was after spending days in the Fiat garage with them trying to find the fault. The air flow meter being knackered was causing the other sensors to register faults so the diagnostic could not tell me anything!

Have you had you air flow meter tested?

Well, i am not sure aboat flow meter, but can i check it without diagnostic?? On first look is like normal.... Cheers

im having a similar problem at the minute. 3 garages have yet to find out whats going on although i dont have a lamba sensor , getting one put in on friday so ill let you know what happens after.

Unless somebody can confirm what is causing this annoyance. :bang:

UPDATE: i had a lambda sensor put in and a few boost cables replaced because they were splitting and so far it seems to be running fine

ok, i gona order lambda as well!!!!!!!! Cheers

did you check the AFM? might aswell do one thing at a time and rule things out one by one..no point spending loads on bits you might not need

AFM is going well..... now lambda is my target
