Sorry i was in a hurry when i posted. O2 sensor had been in for a few weeks. Car was going ok. Had battery disconnected to charge. When i reconnected it the ignition was on and now i have the above problems. I have reset ecu 5-6 times both by battery and connectors under dash. Problems slowly getting worse. Bot sure if its ecu or sensors but definateky caused by connecting battery while ignition on.
