Sluggish

Quicksilvers

I experience the same thing here in Atlanta, Georgia during drive time stop and go traffic because it is all about getting air flowing through your radiator to cool down engine temperature. A larger engine oil cooler will help lower your engine oil temperature. Every vehicle runs less efficient in the hot humid weather though. Have you been doing all the general maintenance on your car? A lot of different things could be wrong with your car as to why your car is hesitation,sluggish acceleration,or lack of throttle response. You could have a clogged internal fuel filter in your gas tank,your air filters could be clogged,you could have vacuum leak/s,you could need a full tune up spark plugs,coils,pcv valve,oil change etc.,you could have faulty 02 sensors. If you think there is something wrong with your car get it diagnosed by your mechanic.
