When driving, i give it gas but it will not accelerate, you give it gas but it wont speed up ?

could be a fuel delivery problem have you checked your fuel filter ? sounds like a dirty fuel fiter.

Does it down shift appropriately when accelerating? Normally when you stomp on the gas while in a high gear (travelling at 40mph), the transmission will downshift to a lower gear giving the car much more torque. This can cause the car to jolt or jerk forward and accelerate suddenly.



If this is way off base and you\'re experiencing something else, please let me know

trans mission speed switch also pull the egr valve and clean it up watch you tube its great info on it speed switch is not sending the right signal it will kill the flow of fuel good luck

Fuel starvation can be caused by dirty fuel filters, bad fuel pumps or a throttle position sensor that is not working properly. If the car drives normally at lower speeds and only has problems at faster speeds or under hard acceleration, I would change the fuel filter first.

Possibly but to find the fault have the fault codes read . It may be the accelerator position sensor . Don't waste money until you have the codes to point you in the right direction

just a seal
check the drive line joints as it indicates a bad joint

try the throttle position sensor as well, wont run you more than forty bucks give it a shot

Could be wheel bearings . Some times they make noise at certain speeds. Even had a vibration with a tires out of balance. I had to get new tires.

It sounds like one or both of the drive axle inner joints are worn out. This condition will give a very pronounced vibration on acceleration only and will be worse with increased speed.

sounds like poss throttle pos sensor prob./ could also be problem w/fuel pump not pumping enough fuel at high speed. poss fuel filter clogging also. have someone check pump pressure.
