Thanks Both - good pointers. Lucas, air filter was recent, yes I had thought about cleaning the throttle body and MAF. Plugs were done at 60k I believe. Vlad, thanks for the tip. Will be putting a scanner on the car when the mechanic comes over for the live data. Car has 77k, FSH, all the oil changes were done well ahead of schedule throughout its life, every 5k'ish miles, very lucky to have found such a good example. Thanks again guys, will pass info on to the mechanic. Chris.

I tried the Throttle body relearn but the issues are as before. Any other help most welcome, thanks.

Very helpful, thanks Declan, I will give this a try

Hey all, I hope someone might be able to help. Two notable issues to describe the problem I am experiencing. It is currently sporadic, it might happen around 50% of the time from a cold start. It's an auto. Owned the car for 16 months, issue started a month or so ago. 1. Car often idles at 1k rpm, even coming up to temp. When releasing the brake pedal to allow the car to creep forward, car surges forward too strongly - enough that if I apply no throttle, the car has gone fast enough to change into 2nd gear once before in traffic. Strangely, I have had situations where the car will idle at 700rpm in neutral, but still push forward strongly when put back into gear. 2. Whilst the car is still warming (I can't say at this point whether this issue might still happen at temp, it hasn't yet), if I am in say 5th gear, just holding a very light throttle to maintain speed at 40-50mph, when I come off the gas, the revs drop down to near idle then rebounds back to the correct revs. I can feel a slight jolt through the drivetrain as expected. My current thought would be a sensor - TPS or Air mass? Thanks for your help, Chris.
