Please I need help with fix cold start isue.
1.After first starting, the engine RPM are unstable 650-1400 and after 10s engine switches off.
2.After the second start the engine will not stop, but the rpm are still unstable until the engine warms up.
Dealer replaced throttle body, replaced fuel pump, replaced spark plugs, reset TPS, replaced ECU, checked oil pump pressure, checked timming.. check valves..
The problem is in the summer but also in the winter.
Can anyone advise me please what could cause bad starts?
