Hi,

i got a fiat bravo 1.4sx mj97 with bosch motronic ecu..

i cant use fiatecu because my ecu is not supported yet.. so i justed kwp71diag from sander to get connection to ecu.
today on the highway i noticed loss in engine.. no more power.. but no engine lights or sounds or so.. so i stoped car.. switched off.. started new.. all fine..

So Kwp71diag gives me:

Hi,

I think that these 2 errors mean the following:
1. Rpm sensor, Intermittent
2. Lambda sensor, S.C. to Ground

However, I'm not 100% sure about this because these old ECUs use weird protocols and data formats.
