Have 94 Accord LXI - First started out with ck eng. lite code 6 - that disappeared. Then eng. starts ok and runs smooths until the temperature guage comes up.... The car will not idle down below 1200 rpm... then the eng. wants to buck when accelerator is pushed down at driving speeds. Is the air/fuel ratio off? Any Ideas? I did ck all fuses... appear to be good.. Thank you in advance
