[QUOTE="delphinium, post: 962506, member: 1332"] I've got this from my Autometer AFR manuals: .. provided the O2 sensor and AFR meter is in working condition .. "When the engine is at heavy load, the monitor should indicate rich. At cruising load the monitor will appear to be bouncing back and forth between rich and lean. This is normal. The computer is constantly adjusting the air/fuel ratio for performance and low exhaust emission" Mine is showing lean at idle. I guess this is due to I set AFC to -7% to lean out the mixture. I just thought that at idle i dont need that much of fuel. [/QUOTE]
