Its allways a good idea to do the filters with the plugs. The new plugs could be improperly gapped. Does the car run the same as befor aside from milage ?

2004 kia sedona ex -just over 100k miles - On cold start after having not been run over night it starts fine, for the 1st few minutes of driving when you push on the gas there is a sputtering/shaking...


It is odd that there are no codes registered. Have the scanner connected while you simulate the condition and get the check engine light.

Since we do not have codes handy I would suspect, bad wiring. Have the fuel pressure tested. The problem may be from the lack of fuel being supplied even if the throttle is stepped on. Check the sparks from all of the plugs. When you check the sparks from the hi-tension wire, do it one at a time to check which causes the sputter.

Other than that it could be loose wiring or vacuum lines. If you have carb cleaner handy or throttle spray, try spraying the intake of the car. At times it may help.

Nothing to do with valve control but o2 sensor should be replaced and also sounds like the engine is misfiring when gas is applied, this may be caused by a bad coil or sparkplug.when was your last tune up?, i would replace sensor and also make sure there are no other codes , even check for history codes.

Is the 60thousand milage service mandatory?


Couple of things on the 60,000 that you should really do replace all the belts and check the rear brakes. No you don't need to go the the dealer unless it affects the warranty. i am pretty sure the Kia has 100,000 mile warranty so you might want to check the fine print on the warranty just incase.

Toyota 2006 4 Runner: What is the recommeneded milage schedule for replacement of the standard factory installed spark plugs?


Toyota recommends 5ys or 100k miles which ever comes first. As a professional mechanic, I recommend this at 3yrs or 80K miles for better performance and optimal gas mileage. Also having the spark plugs on the motor 5yrs/100k may lead to plug seizing to the aluminum heads.

2004 Kia Sedona wont start but i can hear starter.


if the starter is revving very slowly it is the battery, charge battery. if not, It can be three things happing. 1 no spark 2 no fuel 3 no crank signal or the car computer is bad- you will need to unplug one of the spark wires and remove the spark plug and put the spark plug in the spark plug wire boot, and touch the spark plug on any metal on the car and have some start the car. donot touch the spark plug itself and see if there is a spark. if spark is bright, then it is not spark plug and wires but if no or spark is not bright, check the spark plug wires by applying a little bit of water on the spark plug wire and take a 12v test light, connect the clap to ground and and have some one to crank the vehicle, touch allover the spark plug wires with the tip of the test light, if you see spark, replace the wires and change the plugs.. they are not good. if spark is present, check for fuel by removing any one of the spark plugs and see if it is wet. if wet fuel pump is ok but if not go look for the fuel pump fuse and relay. is fuse blown, replace, check the relay resistor with a volt meter. it should be around 40 to 80 ohm. if everything is good from this point check the fuel pump itself by disconnecting the connector to the pump and apply 12v and ground using jumper wires or some wires to the fuel pump if you donot hear the pump,replace pump. if you, the crank signal or computer may be the problem
