Hi.. I'm having bravo t-jet 1.4. No response in bravo thread..so im trying my luck here..
So engine check light up. Obd reader shows one fault
P1684 something with throttle body plausibility.
Maybe someone knows what that means..tia. Have clear the code. But it comes back..then car goes to limp mode..turn off engine and start again good for some time..any help..tia ??
 
Try use original MES, not OBD reader...you can also check/measure on-line data directly when problem occure
 
you could try cleaning the throttle body as a first step, if it looks dirty and blocked
 
I believe that he already did it...

Yes. Tried to clean. Gonna try to open throttle body and check whats inside. My wife drives the car. And she telling me then she in neutral gear car goes in limp mode time from time. But if she in gear and clutch pressed everything ok. Its like second day like that..?
 
Hi. I own a Fiat Line 1.4 petrol from 2013. I've been having a problem for a long time. When driving at speeds over 100-110 km / h, one clip is turned off and the car runs on three pistons without receiving any gas. Immediately I stop the engine and restart it, making the engine run smoothly as I drive up to 100km / h. I changed the spark plugs and cables but again I have the same problem. I did diagnostics but it shows no errors. Does anyone have an idea what the problem might be? Thank you
