Hi. Ive been having problems with the temp gauge on my astra gsi z20let.sometimes it works and gives a correct reading but it very rarely works.
I'm then getting the (control indicator for engine electronics light), then after a while that switches off and the (control indicator for exhaust emission light) this light then remains on
The car will not rev over 4.000-5.000rpm when idle and if i drive the car it starts to kangaroo like mad when i accelerate quickly (is this limp mode?).when the car is idle there is white smoke making me think that the car is running rich due to coolant readings.
I have done the earth mod just under the battery and its made no difference, gauge still wont work.
I have now ordered a new coolant temperature sensor and will try it as soon as and hope this is the fault.
Has anyone else had any problems like this and could give me some advice please.
