Hello guys.
I am trying to find a diagnostic tool for my laptop to connect to the ecu so i can have live data from my car.
As far i have tried ddt4all and renolink 1.87 with no luck.i read here about the xr25 but i don t know if it will work with my ecu.
The reason for all this is that i have done a head gasket repair and ever since i have this strange problem,car starts fine but after a little starts misfiring like it is overfueling only on low rpm and on idle,if i rev it up
misfires stop.All sensors are changed with new ones and only if i unlplug the O2 senosr the problem disappears(O2 senosr is new too).
Also the fuel consumption it too high.Could this be because of wrong timing by one tooth?
