On the way to work this morning, as soon as the car got up to temperature, I noticed the revs climb at junctions and stay there as if I had my foot resting slightly on the accelerator, not revving through the roof, just up to 15-2000 rpm (guessing as rev counter not working at the mo)
It also seemed to do it when in gear and crawling in 1st/2nd gear too. Although it was intermittent, sometime a blip on the throttle would see the revs fall to normal tickover, sometimes not.
I noticed it on the way home too, but traffic wasn’t as bad and therefore not as noticeable
Just wondering where to start with this one? Airflow sensor maybe? Someone at work suggested spraying some carb cleaner into the throttle body. Any and all ideas welcome...
Thanks in advance.
