I have been driving mostly highway miles my last tank of gas, and my A/C has been noticeably cycling a quick off-then-on cycle every 20 seconds or so when driving. When in 2nd gear at 25mph, this is VERY noticeable as the car jerks quite a bit. The local Honda-only place says it's just fine, but I have just gotten the worst tank of gas I've ever had in 60,000 miles of owning the car. 29.5mpg. My previous worst was sitting in Norfolk, VA traffic for long periods of time, and that was 32.5mpg. What might be the problem??? O2 sensor? Evaporator temp sensor?? I can say that both my radiator and condensor are VERY nasty with bugs and tiny pebbles, but I couldn't find a radiator comb that fits the corrugation in the radiator. (It did help with my house A/C though...). Any help would be appreciated!! Nate
