The car ran find until today,It runs ruff at low rpms,better at higher rpms,I have had problems with water leaking down from below the winshield and leaking down into the overvoltage protection relay,the relay that is in the car had filled up with water 2 years ago, but was able to fix it by drying it out with a hairdryer.I should have just replace it.The fuse in the ovpr is ok.The plugs our fine.Does this sound like a ovpr problem.Please help thanks''clark C
