Thanks all. It really is an odd one everything is running fine other than a slightly fast tickover. No evidence to support this but it doesn’t seem like a stepper motor or throttle plate issue? Unplugging the temp sensor increases the revs at about 2000 rpm dropping immediately to 150 on reconnecting. I’ll try the east start recommendation as there’s some in the garage (thanks for the H&S advice!). It “feels” like an incorrect ECU setting. It’s feeling like a trip to the dealer hopefully before its SORN kicks in
Thanks again
