hesitation when car is hot and air temp is hot I hope someone can help me. I have a 1994 25th ann. t/a. the car is totally stock with 106000miles. I drive it everyday. It has been 99-103 degrees everyday for the last week or so and the t/a runs hot anyway; 210 and above while in traffic. Once it gets to that operating temp. it stumbles and hesitates from 1500 to 2500 rpm very badly and starts to develop a rough idle when at a stop light. She runs great when the engine is cold and or the outside temp is below 90 or so. I have replace the coil, plugs, wires, egr,fuel filter,etc. Help me!

possibly, no check engine light ever comes on though. vapor lock? i did smell a strong smell of gas on the driver's side and noticed some nasty black ,"spillage," coming from the gas lid area. maybe a bad or blocked vapor canister or vent tube?
