Can you be more specific, like engine size, transmission type, vehicle mileage, does the engine rpm's fall or flicker when start to "jump and jerk", does it keep doing it above that speed or stops beyond it. I am trying to determine if it is an engine or transmission problem. But I need details.

SOURCE: front end shimmy over 60 miles per hour

If you are experiencing a "shimmy" that only occurs at a certain speed, I'd suspect a tire balance issue. If it were in the alignment, the problem would manifest itself at all speeds not just at 60 mph. There's a chance that a wheel weight fell off or the tires have uneven wear. If you do have uneven wear on the tires, then you may worn front end parts that need to be dealt with. Incorrect tire pressure can cause uneven wear as well. Hope this helps.

SOURCE: Won't accelerate past 40 miles per hour

these jeeps did have a small problem with the tp sensor. i would also have the back pressure of the exhaust checked to see if you have a catalytic converter choked up.

SOURCE: Check engine light intermittently flashing, car jerking.

Could be fuel or electrical related. Since you may not know the history, this may take a while.
Any amount of smoke from exhaust? White, Blue, Black?
Start with most obvious and inexpensive:
1. Fuel filer clogged (replace fuel filter).
2. Could be the ECM (Electronic Control Module). It controls the ignition spark timing.
A few other things... consider other expert solutions...

I have a 2003 dodge intrepid es with the 3.5l motor 1 day I was driving and my car over heated and just shut off when I lifted the hood the radiator hose was busted I finally got it home and opened it up...

You need to find out what fault caused the check engine light to come on, until the fault code is retrieved from the engine control module memory you are 100% guessing. I think you have a misfire.

Car is jumping while excelerating at 40 miles per hour,stops jumping for a few minutes then starts jumping again at 55 miles per hour

Start with changing fuel filter, then if that doesn't work, your fuel pump may be going bad.

Intermittently the car will not go over 25-30 miles per hour with the accelerator floored. Other times, the car bounces really badly as if it had a blown front tire (not) or totally worn out shocks (

Hi I am Vortash have seen this fault twice with a different reason each time .. first on was the cam sensor giving the wrong information to the Engine management Unit ... second one was the EMU itself the plug had become dirty and corroded and a clean solved the problem .. with the cam sensor ..was replaced and the fault cured .. The way I found the fault was with a fault code reader an invaluable tool that has saved me many hours of unnecessary work ... regards Vortash

Engine Light on - Jerking when i get to about 45 - 60 miles

get your trouble codes checked with a obd2 code reader. most auto parts stores will do this for free it is the only way to know for sure what is causing the problem most mechanics will charge for this service. it could be anything from a fuel filter to an ignition module it sounds like a misfire but without the codes it's hard to tell. hope this helps
