so I'm driving around an on ramp and come onto a main road. I downshift to second and punch it. well the car starts to go, and all the sudden my car stops sucking air. my car did not respond. I take my foot off the gas pedal, and try it again and its works but the engine lite goes off. The air outside was really dense, could that have anything to do with it?

I checked under the hood to make sure my intake, and the vacume line were attached and everything seems ok under the hood. Anyone know what could have happened? I'm thinking of droping it off at the dealership and have them do the 90000 service early, and change my timing belt. My car has about 87000-88000 miles on it now. anyone know what I should do?:wtc:
