Thats the thing,when you first start the car i the morning it will pop and burble like its not getting enough fuel it takes about three cranks with the gas floored then the engine wil rev up then I can let off the pedal and it wil idle about 300 rpm's for 3 min and then it raises up to normal idle and is ready to drive would the IAC cause this? the ac doesn't work so I dont have idle change with the ac on When the car is warmed up about five minutes it drives/runs great theres no check engine light

Hello,new to the forum great site,I have a 92 SC300 I just bought it has its eletricial problems,but iam stumped on why it starts so hard in the morning its got a JDM crate swap in it.The guy I got it from just had it in for a head gasket replacememt caused by a bad radiator the shop he took it to did the work but didn't put the themostat back in?So the temp gage only gets a hair above cold In the morning its take three or four cranks with the gas all the way down,the engine pops through the air filter like trying to start without a choke eventually it will fire and ill have to hold the gas at about 1500k for too or three minutes to warm then i can drive it. I want to replace the thermostat but want to do any sensors at the same time if they pertian to the hard cold starting that are in contact with coolant so I don't have to fill the rad twice.Any help on this would be great.
