Question about 1998 GMC Sierra

1 Answer

My 1998 GMC sierra 5.7l vortec has the distributor placed directly under the vent at the bottom of my windshield. When it rains for a few days water gets in the distributor vents and causes the truck to spit and sputter while excellerating. other than changing out the cap and rotor every oil change is there something I can do?

I have a 1998 Chevy Suburban.whenever it rains the driver side floorboard becomes wet. door seals are good. where could the leak be coming from?

Possibly from the windshield. Is there any rust around the windshield area? Check for debris in water drain outlets under the wiper arm cowling.

What causes water to leak into the interior after rain?

Are you saying the water reappeared while the car was still in the garage? Hope this is not true, as that would most likely be related to the heater core or plumbing, but I thought all that was on the passenger side. If you mean after putting the car back outside and in more rain, possible cowl vent tube leak, windshield leak, or door vents at bottom edge blocked with debris.

1998 318 Dakota hard to start in/after rain

Check the distributor cap, u can have a very fine crack that allows moisture to enter on damp days and make starting difficult. Look inside cap w/ good lighting, u can usually see it if u look carefully. Let me know what u find.
