Hi Guys,
just wondered if anybody could shed some light or offer any advice to why my 2004 1.2 Panda is playing up.
Problem : When started from cold the engine vibrates a lot as if it is misfiring and you can feel the car hesitating when driving. After a couple of minutes, the car feels much better although still seems to be misfiring. Occasionally the Engine light will come on although does not seem to go into any limp mode. Reading the fault reports 0172 which using the Torque app suggests running too rich and connecting it to the free version of ECUSCAN shows lambda 1 & 2 rich. Car has no problem starting cold or hot and returns 48mpg according to computer.
so far, I have replaced with no change :
Both Coils
Spark Plugs
Leads
Air filter
Thermostat
and have also cleaned throttle body butterfly and ECU connectors.
Oddly, when it throws an ECU error, it is always when idling and after a few days goes off on its own.
I did wonder whether the Panda has an engine temperature sensor separate to the one that controls the dashboard gauge ? this would maybe explain why the car is trying to run too rich ? and maybe not leaning out the mixture once the engine has warmed up.
anybody got any ideas ?
