Weird problem
 

Randomly my 86 N/A will start up fine but when I give it gas the rpms hesitate or go up only alittle and then drop. When I put it in gear and try to drive the car will start to go for about a second or two and then shut off. It seems like it has something to do with water getting in somewhere because it happens 99% of the time when it rains but this morning there was some condensation on the windows and the same thing happened after I let it warm up for about 5 minutes. Does anyone know what this could be???

So the car works fine when it's dry?

Check all the connections around the ignition coils, and examine the coils for signs of arcing. Check your plug wires.

Clean and check the connector at the CAS. Use contact cleaner and carefully examine the wires for a poor connection or cracked insulation.

Yea the car runs perfect when its dry out but okay will do. thanks
