OK, it came in because the battery warning light flicked on, so it sounded like charging, but it is actually that the idle goes too low and then recovers.
Any ideas on what the likely fault is. W plate 1.6 16v. 78,00 miles. No trouble codes at all.
I am going to start with a vacuum leak hunt, go on to a throttle body clean, then see what the MAF is doing and the TPS.
Any bets on the fault?
