my mums P-reg fiesta 1.3 has gotten even more gutless than normal recently.....

checked the CO and it was around -0.5 - 0% CO at idle.

It's EFi so I guess I can't adjust the mixture? Which would suggest lambda sensor?

 

-0.5 %


???

glad u could diagnose a 1.3 is "gutless".

would be hard for me IMHO

i know when mine is "quicker" than normal, and "slower" than normal, but reckon its due to intercooler soak but thats on an rst

i would be struggling on a low cc n/a motor

 

trust me its quite obviously slower than before!! theres just nothing there....!

Alex....yea sorry i meant its basically bang on 0% cos the gauge is +/- .5% so that kind of confirms if its -.5 out its still 0 (if that makes sense )


....maybe it is actually okay, not sure what the co should be but i would guess 0.5-1.0 or at least more than it is? otherwise any other ideas for its apparanty lack of life.

air filter is new'ish, all serviced up etc

 

CO sounds right...

If its a HEGO the fuel econo will drop loads...

ah okay fair enough must be elsewhere cheers alex
