yea well this same problem happend to me a few days ago, washed my car, went out for a drive
started it agian a few hours later, (it was raining)
n it sturggled to start, when it did there was loads of strong vibrations, the gear stick was wabblin like anything.
it had no power n the
engine warining lite came on n then it stalled.
called green flag n i had to get towed home 150 miles
i took it to a garage the next day n they ran a diagnostics check n found out that 2 of the 4
had gone ka put so they are changing all 4 for peace of mine, n they said it mite b because of the damp and the fact that the car has done 44 thousand miles without having them renewed.
sucks really the parts cost 35 quid each =[
