I have a 1998 caravan that hesitates and feels like loss of power when i take off from starts. It jerks and it feels like its a fuel problem but i took it to a mechanic and fuel pressure is fine and I replaced the pump and filter about a year ago. The error code for bad cam sensor and crankshaft sensor came up so the mechanic replaced them. It ran fine for about 3 weeks but now its doing it again. At first it would only surge when the gas was below half a tank but now it does it all the time. My gas gauge also doesnt go all the way down to empty, it will run out of gas at about a 1/8th of a tank. Any ideas of what the problem could be?

 

It actually feels like your on a bucking bull or sumthing when you full off, its pretty embarassing lol

 

Probably the harness for the crank sensor is rubbed through and shorting out

 

Could be the wiring like tizzy had said, but i going to add maybe the flex plate? You could also have a problem with the sending unit. Also should have the gauges calibrated.
