mark do you really think that i, in any way, can fix this car by myself? it's just that where i live there are so many porsches and so little porsche mechanics and i have an appointment for next week, so forgive me if meanwhile i asked a couple of questions to put my mind at ease and i'm sorry if i have offended you in any way
but overdrive seemed to understand what i meant!
thank you overdrive and i think you are right the whining is probably due to the bumper hitting the ground, as for my backfiring problem i will get back to you as soon as i know anything.
