Yup that was it. Now the other issue I'm sorting is that if I tow I get a P0155. I have replaced the O2 sensor Bank 2 S 1 and it goes away with removing the battery cable. If I tow again - the light comes back. Temperature seems to be normal. I did think of replacing the Coolant Temp Sensor (Amazon sent the wrong one) and noticed that with the AC on the condenser fan wasnt getting warm (assuming its not running). I unplugged it and its still moving which is due to air being sucked from the rad fan. Could a bad AC fan cause a P0155?????
