My 95 caravan 3.0 starts up fine, but when going up a hill acceleration is sluggish then when coming to a stop the engine stalls. this is an intermittin problem but is getting worse now. Fuel filter and new factory fuel pump have already been installed. no check engine light on though. any help or suggestions would be great.

Have the timing checked , it make have jumped a tooth on the timing belt if it's been awhile since the timing belt was done .

actualy just replaced timing belt about 4 months ago. mabey just needs to be timed? i did everything by the book

If the timing is good, try one of those cans of throttle body cleaner. Others on this forum have had good luck with them on similar problems.
