Problem 1 : When taking the car out in the morning it starts up fine no problems at all but when I get on a straight road and put the foot down the power goes fine then suddenly stops/pauses for a few seconds (around 3000 rpm) and then the power returns. After its done this once or twice it usually doesnt occur again.
These codes came up on the laptop:
00635 - Oxygen Sensor Heating Circuit - Ahead of Catalytic Convertor
00522 - Engine Coolant Temperature Sensor -G62
00525 - O2 Sensor - Voltage Low -G39 B
I changed out the temp sensor for a new 1 and that made no difference. New lambda needed?
Problem 2: When I reverse and smoothly put on the brakes I get a dinging noise. This happens anyway of turning and also straight back but doesnt happen at all when going forward.
If any1 has any ideas for any of these problems its much appreiciated
