its a bse 1.6, 2006 . drives perfect, mint condition, full history, new leads, coil etc..., ideal little low mileage car with a recent timing belt. but, turn it off, start up again, pull away, change into 2nd and it bogs down. back to first and its off again, or , change upto 3rd and its off again. only ever does it once or twice when started from hot or cold and only ever does it in 2nd gear. tb has been cleaned and calibrated, as has the egr valve, so come on, help...
