    Get it scanned properly coolant temp sensor can cause revving up when starting, so it could be a simple cheap fix £20-30

    did you check the actual values on the position sensor with the diagnostics?

    doubtful its that tbh.

    vac leak or pcv valve more likely if you have no fault codes.
