Car jerks when picking up speed, its almost like a miss

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

ever do a 60k tune up?
do you need the list? its in the operators guide in the glove box.
fresh spark parts.
filters, all.
and new timing belt (no engine stated so....?????)

If the engine has a rough idle you know you have a miss-fire or other problem with one or more cylinders.
When you shift into overdrive the engine is working harder than in normal drive because of the lower torque/RPM.
So any slight miss under normal conditions will be magnified in overdrive or with the ac on.
See if you can nail down the cause for the rough idle.

Hi there, it could be a change of spark plugs will solve your problems. I'm driving one too but found that it jerked when accelerating. So I read up and presumed that the old plugs might be the cause. After changing new spark plugs, it doesn't jerk anymore.

fuel pressure cud be bad at that speed--transmission may hav issue in top gear--find a specialist to test--------

sounds like possibily crank sensor or cam sensor

Spark plug wires

is the check engine light on?

Make sure you do not have any vacuum leaks and the egr is functioning properly. Next do a compression check and see if you have a low or dead cylinder. I hope this helps you to find your solution. Merry Christmas! and God Bless!

Just got the same problem fixed myself. i thought it was the coil but turns out to be spark plugs and split breather hose in the engine!
