Alright guy's i need some help i have a 93 ford explorer and she's been running great all summer but as usual when the cold get's around all car's start to act up. Well here's issue im having in the warm or hot day run's fine no issues driving at all. Now let's say it's 45degrees or colder out will have problem idiling or when i go to put in reverse or drive it chugs etc...like want's to die. Now i've done number things to this truck. Here's what i have done
*brand new spark plugs/wireset
*Ect(engine coolant temp sensor)
*Iat (Intake air temp sensor)
*Iacv (Idle air control valve)
*Purge valve solenoid(This deff helped with the driving normal issue it was having it run to lean and wouldn't have no ball's at all but i fixed that issue)
Part's ive checked igntion coil sprayed water at night getting no arch or spark. carb spray old skool trick no vaccumm leak's , Maf(mass air flow) check's out good as well.
Now i have read on newer 4.0l sohc motor's lower intake gasket/upper also will do this drivability issue? anyone know if this is right for a 93 i would think so because same motor. Someone please help me this is my daily driver as well and winter will be here soon
