92 caravan update

same 92 caravan as 2 threads ago. i'm wondering if maybe it's the fuel pump as some other people kind of describe the same problem. the car hesitates, speedometer falls to zero and right up again. sometimes i'm bucking and bronking 3 or 4 times in a row and sometimes it goes for days without a hitch. it sometimes also stalls when i go around corners and don't have the gas pushed down. please help.

Check the egr valve and that hose that comes out from the exaust manifold, they get carbon crusted.
