I need to know how to reset the ignition timing on the ECU of my 1989 Honda Prelude SI. The problem started after a new timing belt was installed by a local shop. The engine ran fine for a while Then after a few months, the engine developed a loud clicking noise. A few miles later the engine power dropped dramactically When I removed the valve cover, I noticed that the bolt holding the rear cam sprocket was loose and had come undone by about 0.2 inches. I thought that the noise was the sprocket moving on the camshaft spline. I tightened the bolt and adjusted the valve clearances. The engine started, up normally and the noise had gone. The power, however, was still pitifully low. I noticed that the power got worse as the engine warmed up. The plugs were sooty. It sounded as if the engine was severely retarded. I connected a timing light and confirmed this. I followed the shop manual procedure for setting the timing but there was not enough adjustment in the distributer mounting to bring the timing to 15 degrees BTDC. Then I think I made a fatal mistake. I restarted the engine with the shorting plug still in the yellow timing socket. Now the timing I need to know how to reset the ignition timing on the ECU of my 1989 Honda Prelude SI. It backfires and sounds like hell.I tried to reset the ecu by disconnecting the battery and by removing the clock fuse to no avail. Surely I don’t have to buy another ecu. And why did it happen in the first place? The check engine light works normally and does not come on. I checked the MAP and the coolant temp sensors and they seem to be working normally. Can any body help?

Hi - I've always heard that it's good to run your air conditioner a little bit now and then, all year long to keep seals lubricated. In the winter time, does using the air conditioning as a heater count in keeping all of the seals lubricated? Thanks
