When I accelerate, the car bogs down, it is worst in cold weather, and always stalls when it rains. Any help will be great!. tHANKS

 

The problem is caused by moisture. So Im guessing its gotta be ignition. Test your plug wires for resistance, replace if too high. Or if its been more than 30,000 miles since they were changed.
Remove distributor cap and rotor, inspect. They're probably worn out. So change them if they are.
