Two problems.

Hello, my daughter has a '94 6cly and I changed out the cap/rotor/fuel filter.

The van was given to her and has about 150k on it. Doesn't burn oil/no leaks/runs ok besides the problem I am having.

1. When you depress the gas pedal there is a hesitation to where the motor drops off (dead spot/zone). If you feather the gas pedal it will do fine and get up and go. I can hear the fuel pump engage so i don't think it's that.

I was thinking it might be the vapor canister that maybe clogged but not sure. When I go to accelerate the throttle manually buy hand under the hood I can hear a click, I put my hand on the vapor canister and it clicks from the valve on the top but won't do it again until the rpms drops to idle.

Just don't know where to look.


2. The power windows do not work, fuse is good and continuity checks out but windows will not operate. Is there another fuse somewhere else beside the one on the divers side fender under the hood. I did look at the pull door on the dash but it did not list the windows. Power door locks work though.

Thanks again,
Jim

 

Fixed it - MAP sensor

 

Mine does the same but boost of power at 3000rpm, and is hard to start when cold and fine when it's warm.

 

Had similar problem. On an old battery, ignition can pull down voltage. Check out ignition circuits, in including battery and fuel shut off switch ( corrosion, spiders)
