Nissan was experiencing gas mileage/acceleration issues.I pulled into work & noticed steam coming from under hood/front grate where radiator is.I looked under hood & antifreeze fluid was every where & the top of the radiator had fluid pooled up in the metal groves.I still had fluid in my reservoir & cap.I took my car to shop w/pictures & they told me the seals on the top had gone bad so they replaced my radiator.Then my gas mileage was worse so I took it in for spark plus & diagnostic testing.They could not find anything.I have never had a check engine light either.I picked car up & 30 miles in my car stalled once w/ac on.I pulled over popped hood & found my air intake hose was split.I replaced that myself & my gas mileage is good but the idle at cold crank was 1200 & took minutes to come down.idle rpms is good but using ac drops them extremely low to point of almost stalling.replace crankshaft sensor.high idle good now low idle still issue with ac on
What makes this problem better or worse?
Running ac makes it worse.
