I have a 96 Legecy 2.2 with about 97K. It starts fine and runs fine for about a minute or so or until it reaches operating temp. Then it start to miss and does so for about a minute then clears up. I have change the plugs and wires. I have checked the injectores for pressure and pulse they are fine. I have replaced the knock sensor no help. I put a different computer in it and that made no difference. The only code that comes up is misfire on cylinder one or cylinder two, usually on number two. I also checked to see if a valve quide was loose as I heard that sometimes happens on this year. If it would not clear up maybe I could figure it out. Has anyone had this problem or have any suggestions?
