I just bought a 99 gt convertible.Odometer says 83,000 Guy i got it from said that its overheating and has loss of power. He said he brought it to local service center and was told head gasket was bad. P.O. said he just changed intake manifold because it had crack in it. It does have new manifold.
Well i got it home and it runs strong with a slight miss. Doesn't smoke and oil is not milky. Well i was thinking maybe he got coolant in spark plug hole and maybe that was why it was missing. So I started disconnecting the coils one by one and engine would miss until i got to the #7 plug coil. It was different has gray sticker instead of yellow. I disconnected the plug and no change in engine. I got my meter out and it was 1.5 ohms. Does 1.5 ohms mean its good??
