sounds like it is loosing vacuum check all the lines for a crack even the engine lines will cause it to loose vacc. pressure. if it is not run to the vacuum reserve canister you may not have enough vacc. to hold the actuator in several times I just run new lines and that helped and not very costly.

My 89 Cutlass had a strange starting problem too...During cold weather she would crank, but she would not start...I could heat up the top of the engine with a hair dryer and she would start....Shop finally fixed her, replaced the COIL, the old coil was no bueno in cold weather!!!!
