VF750

Yes, at great expense from a Skoda dealer 😳 A year old. Car’s actually well looked after for an oldie (13yrs) but different garages can’t find anything (nothing on the diagnostics).

Thanks, CTS changed a month back and initially it ran smoother but seems back to ‘usual’. Will look at the lambda 👍

It’s a 16V (59kw?) manual.

Given mixed driving, what fuel consumption is reasonable to expect? Currently about 35/36mpg.

Fitted the new sensor earlier today - it was the 2-terminal type. Not a hot day today and it started and re-started fine afterwards. My wife drove it later too on a routine journey and without any prompt said the car feels smoother. The tickover is more even, noticeable at the first start-up after fitting, and it feels more responsive generally to drive. Filled it up with fuel to see if the MPG improves in the days ahead, as it may well have been running generally richer than it should. Main fault was the poor restart on hot days so may not get a proper check on this happening for a while. Well, it is summer

Got a new original Skoda sensor today and plan to fit it this weekend. This process alone has sent the hot weather packing! Will update once I have info to report. Thanks for the constructive help in both the posts above.

I run an 07 late Mk 1 1.4 petrol Fabia, which intermittently won’t start when the external air temperature is up in the 20C+ range. Always starts immediately usually and shows no fault codes at all. Seems mixture related as it smells ‘petrolly’ when it happens. Green Flag showed us a get-round which works every time it plays up by holding the accelerator down and turning the ignition off and then on. It's only an intermittent fault. Any clues anyone please? Car’s well maintained and done 5K miles since its last service incl new spark plugs.
