Kia Sportage jerking and sputtering

sputters in the context if engine, means MISFIRING, is it?

for a transmission, they dont sputter. sorry

but can jerk, or snatch, (being caused by gears engaging way to late)

(aka, harsh shifting) the opposite of slip

but it can slip then engage, causes a jerk. or harsh shifting.

see?

they do 100 things wrong, mostly never to sputter.

they don\'t shift up or down

they slip. (bad tranny)

if engine sputters, its tune up time, (posted like 10,000 times here)

if the transmission has issues, have real mech test it and tell you

all the symptoms, and possible ideas.

why not?

the A/T is a very very complex electro /mechanical device.



sputter is a word best for engines. like chain saw with a bad spark plug it sputters along and stalls.

does your car stall?

fuel filter may be on backwards, restricting fuel flow, if not that check that the spark plug wires are on in correct firing order, as well as the spark plug gap. (spark plugs are not always gapped for the particular application from the factory due to the multiple array of applications a particular plug can be used for)

Hi Missippirebe, I think you should replace the fuel filter and if the problem persists check fuel pump pressure. It should be at around 3.7 bar. Regards John

You'll have to figure out if it is a fuel or ignition problem.
Is the check engine light on ? Have you checked for trouble codes ?
It could be a coil, spark plugs, fuel pump, fuel filter, or a list of other things.

you are still under bumper to bumper??? if so dont mess with it take it to dealership. if you mess with it .it can void your warrenty

check the last gasket that was fix wasnt too good so replace again

2001 kia sportage, 164,000, driving on highway and engine starts to sputter momentarily, then runs good , then sputters, runs best if you barely push gaspdal, to much pedal and sputters again

Clean out clogged fuel injectors

try putting some prestone into your tank.

If you took the M.A.S. (Mass Airflow Senor) off check to see if you put it backwards. Its has a arrow and shows you which way it goes. Hope this helps.......
