My Kia is sputtering and stalling any ideas? - 2001 Kia Sportage

I would clean the inside of the throttle body first. Back of the plate and where it seats. Doesn't clear up. Check compression next. It is a 2001.

check the engine temperature sensor ?

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?

How many miles? I am NOT a mechanic! Sounds like possible timing belt/chain jumped a tooth. Or the timing advance mechanism is malfuctioning. (Unlikely - check distributor is tight or not shifted from normal position too far back or forward.) Assuming belt and not chain, 80 k miles or more, likely need to replace timing belt in any case, before it breaks. If it breaks, you'll be replacing valves and pistons too.

As you have replaced all the obvious things that could cause the symptoms it may be a good idea to have a cylinder compression test done , if comes back OK i'd try a fuel addative , one that covers the catalytic convertor , as there are many sensor's involved in the fuel/exhaust system as you know , this addative will clean any residue affecting there reading's , hope this helps

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

try your idle sensor or mass air flow sensor

dear friend-to me it sounds like you have a intermmitend spark,it could be that your plug lead sparkplug or coil pack can be at fault,fuel gets injected into the cylinder but only ignites every second time around meaning two injections one spark in an overfueled cylinder,please be careful the back fire will damage the airflow sensor

When was last time plugs & wires checked or replaced, as well as fuel filter.

everytime i try to start my truck, it turns over then stalls out on me. any idea?
