no mate if they **** up they usually go to a default setting. ps im going by modern day stuff if your car is a bit old it might not but i doubt it will cause any damage.

Cheers!!!
Not my problem then, on to the next thing that it might be!! |
Your lambda sensor controls closed-loop (off boost) fueling. If it has been faulty for a while, you will have been running slightly richer than normal, depending on how knackered it was. As the sensor gets more and more knackered, it generates less and less voltage, which equates to reading leaner and leaner, and so requests more fuel to be added next cycle. If you had an AFR gauge, it would probably show about 0.25v to begin with, dropping lower and lower over time, instead of the usual flying about all over the stoich area.
I don't think it will have caused any harm, as we're not talking massive amounts of fuel. If you were excessively rich in open-loop (on boost) however, you could potentially cause damage through bore wash (oil washed away from the cylinder bore by the excessive fuel)... |
cheers for the info lets hope it hasnt caused any damage so i can have some happy motoring :D :D :D :D :D :D :D :D
