Coming to the end of a resto of my Techart bodied C4 and it is up for sale.
Some months ago i had the mixture setting reset as it was running very rich. I was advised it needed a run of 20-30 miles for the ECU to "learn" the new setting and sure enough after a run it was obviously running smoother and was very economic. As I rarely use the car the battery has often going totally flat since then and i now find the mixture has reverted to being very rich with lots of black smoke which is likely to put off prospective purchasers.
Is it normal for it to default back to rich with the battery being flat or is there another likely cause.
