Car Jerking and Jumping?

"Jerking and jumping" generally indicates a misfire or skip - it may also be a lock up converter concern.

If you very lightly touch the brake pedal (just enough to activate the brake lights) when it's jerking and the jerking stops - you have a converter problem. If it continues to jerk along, the engine is misfiring.

If it has not had a tuneup for a few years, that is a good place to start. My other thought is a dirty fuel filter, since the acceleration to highway speeds calls for a lot of fuel flow. Fuel filters usually aren't even called out as maintenance items so I wouldn't be surprised if yours is 13 years old. Unless it has been changed in the last couple of years, may as well have that done now also. I think between those two things you have a better than even chance of fixing the problem altogether, and they are good to do anyway.

my guess its the transmission, change the transmission fluid first. but let a good mechanic tell you the problem. since its alot of miles than change regular gas to surpreme to clean the engine from jerking.

in line with threat a test of the vehicles workstation will take place a difficulty code. it sounds like some variety of gasoline or spark difficulty. you assert it happens wager 60 70. Then its frequently at intense speed? Does it ever hapen at low speed?? like 30? in case you e mail everyone confirm you deliver a replica of the orig placed up.

I'd suggest getting the car to a shop that does diagnostics. Explain exactly what you said here and pay them to troubleshoot the problem(s).

It's either your transmission going out or you need to have the spark plugs replaced

Transmission probelm?
