So when I'm driving wether I'm flooring it or just driving normal my air fuel is fine and seems to be where it should be except when I'm going along say on the highway (that's when i noticed it) but if I'm driving down the highway and if I completely let off the gas in 5th gear my air fuel ratio jumps way up to 18.0 (the max the RPD goes to) it doesn't do it in 4th tho. Is this normal? I seen that with ratios that high could be caused from misfires, is this a possibility in this cas? It's only in 5th and when I completely let of the gas tho, just got the car a month ago only has 32,700 miles on it.

Yes when u go off the gas ur closing off the throttle so little air but still a lot of fuel for a moment, so it would go rich. Mine goes to -29 when I let off
