I have a 1986 Toyota Celica GT (2.0L 2-SE engine SOHC, auto transmission) and noticed that the timing is set to about 25 degrees before top dead center, when it should be at around 10 degrees BTDC. If I move the timing down to 10 degrees, then it runs horribly with no power whatsoever.
I am measuring the timing with a timing light, so I know that it is the exact timing going to the spark plugs. Also, I checked all the ignition resistances and they are within specifications.
Does this mean that my timing belt is off by a notch or two, and so the ignition timing is advanced to follow the messed-up valve timing? I can't think of any other possibility than the camshaft timing being off.
have the same problem?
