    So that lasted about a week lol... I used my A.c and everything it was doing started happening again.. rough idle w RPMs going up and down between right below the 1 and up to the middle of the 2,no power behind gas pedal,super long/slow shift from 1st to 2nd and 2nd to 3rd and trying to run hot. I almost couldnt even get the car to start after parking for 15mins for a haircut and comming back out i had to try like 4-5times to get the car to start and stay started. Burning smell back comming from bottom of engine again also. I obviously turned the a.c off once i noticed all this and once it was off it chilled out but what the actual **** is going on here?My mechanic did say my radiator was clogged and my radiator cap was done for but it wasn't letting air into the system. So could it allllll be my radiator this whole time or maybe something else? What else would cause all of this to happen from simply turning on the heat or a/c?
