Jerking accelerating while driving statring problem on praking

Sounds like a misfire. But honestly it could be anything. If the check engine light is on that could point you in the right direction

we cant drive car, so jerking is not clear to a non driver.
see>?
first off , ill guess there is no odd noises.
and that means jerking can be 2 things (sure more but)
engine jerks, does it only?
or transmission slips then stops slipping resulting in a jerk.

get it serviced, with persons that can drive and experience this live.

similar problems: After 20min cool down jeep was bucking/lurching that I traced to bad o2 sensor in exhaust manifold (which you've replaced is seems). The second problem of bucking/lurching, backfiring under certain driving conditions I traced to the battery sliding into the computer wiring harness, disrupting sensor input / output signals. I cured this problem by placing a 1" spacer on rear battery clamp, pushing the battery forward. Been years and no return of problem.

The first thing you do is to have the fault codes checked with a scan tool.

hi,

check the transmission fluid. if its not this then I would suggest taking it in to a parts store to have the codes pulled on it..jm

Hi,
When was the last tune-up done? Should be done every 30-45KM, or depending on what your owner's manual maintenance book states.
1. Spark plugs
2. Spark plug wires
3. Fuel Filter
4. Air filter
5. Oxygen Sensor

If these have recently been replaced then do you have Check Engine Light (CEL)? If so, you'll need to get that checked by a mechanic.


GL,

i think this is impossible to tell you without being able to drive the car.things are more complicated then we would like. the fact that taking off slowly also causes this jerking seems to eliminate an enginge missfire which would be the first thing that would probably cause jerking. does it feel like the rear prakes are sticking on thi can be a problem with the parking brake cables rusted inside ther casing.four wheel drive problems could be a u jouint or drive shaft issue. have a mechanic at least drive it to get som feel for where the problem is.

clean mass air flow sensor check for mil light

I would look for a fault in the ignition system such as a cracked spark plug. Might need a scope check to put your finger on the problem

I had the same problem It was the wiring harness the top half. Approx. 250 U.S. Dollars
