Symptoms arethere almost every journey - set off everything fine, after 5-10mins ignition light comes on (sometimes after a bump or sharpturn suggesting a connection problem) and then no power below 2000 rpm - requires clutch slip to get car going - throttle response under no load is VERY slow too. After another 5-15 mins the light will go out and engine retunrs to normal.
I've checked connections.
I've hooked up to alfa diag - it shows both lambdas have a sensor heating fault. The output from lambdas looks OK in alfadiag MAF out put looks OK. Haven't tried alfadiag with fault light up
The fault code does say that engine light NOT switched, which is weird, suggesting a different problem?
