I have a problem with an 88 2.3 normal aspirated. When it has sat overnight in the garage it only runs on 3 cyl for about ten minutes. After that it may go on a solid four, or it may miss. The tach also shows the R's at about 1500 over the real reading. The tach swings down when the 4th cyl fires. Where do I begin looking. It has 208k on the clock. I want one more winter out of her. Thanks
