Thermostat seized, overheated, head gasket blew.
Replaced head gasket, thermostat and CAM belt. Palio started 1st time, but after revving a few times, it started 'hunting' and never stopped!
I found one little air pipe disconnected(vacuum pipe) at back of carb - reinserted, idling back to normal, let it idle for about 10 minutes then switched off.
Next morning started car, and it was hunting again, drove car to work for 2 days, but it was revving like mad at traffic lights.
I removed stepper motor connection, and idling went up to max - put it back again, and was hunting again.
I removed TPS sensor (to try and control throttle with normal accelerator pedal movement)and drove for about 2km(without TPS), then car cut out with no power(hazard lights working, but no other electrics).
I replaced TPS at side of road, but still wouldn't start.
towed car home. I removed and cleaned throttle body - blasted with carb cleaner - looks like new.
The stepper motor was gunged-up,also cleaned it with carb cleaner.
Put everything back together, now car turns over but won't fire.
I can hear the petrol pump, and smell fuel in the carb
(every now and then there is a sort-of faint 'cough' as if it has mis-fired
but it won't progress to actually firing)
I have followed 4 different methods mentioned in various posts about resetting the ECU, and it doesn't seem that any of them work for me.
Any ideas - it seems like a variation on a common Palio problem with erratic idling ?
