i'm having a bad luck weekend with my car.....with this particular problem my idle is terrible. it won't stay at one rpm, just keeps dropping almost to the point of dying sometimes and then going back up only to drop again, almost bouncing. also, sometimes when i'm driving and coming to a stop when the rpms are at idle the car will stall when i push in the clutch. other than this the car is running strong throughout the rpm range. mods are in my sig and i don't think they have anything to do with the problem. the msd box is currently not connected and i checked the coil and it was fine. today i cleaned the mass air element and sprayed carb cleaner in the IAC and neither helped. does this sound familiar to anyone. bad tps, iac, egr? some type of sensor? my engine light is not on
