UPDATE(2) 1999' RAM "Speed Sensor Malfunction"

Q: i just bought a used 94 dakota v-8 4x4 with low milage. the gas guage is moving all over the place. i mean it jumps from empty to full no matter how much fuel is in the tank. how can i fix this problem. is this something that i can do myself or do i have to take it in to get this fixed. can anyone tell me what kind of gas milage i can expect since i do not have an accurate gass level reading .

tbone wrote must you always be an asshole while it does not produce torque it doesdeliver it to the rest of the drive train. changing the gear ratio like he said will reduce the amount of torque the transmission will have to deliver so what he said is still valid. what is not valid is the ridicules gearing he recommends for what amounts to not that much work and the way it will kill the trucks mileage for little benefit. tbone i do take exception to the deeper gears killing mpg. a big truck with a small motor and od needs to rev up a bit to get in its power band and nearer its torque peak because it is at and around torque peak that a engines ve volumetric efficency is it highest and it is also when it uses the least amount of fuel per hp hour produced. even with a 4.56 in od it will turn about 2200 rpm at 65 give or take. i doubt that since i have 3.55 gears and run around that level at 65. lower rpm does not alway equal better mpg and usually mean bad performance too in a truck. a diesel can do well at low rpm because its peak ve is at a much lower rpm than a gas engine. i have a 89 4x4 burb with stock 29 inch tires and 3.73 gears which should murder mp
