SOURCE: Engine Check Light - 2006 KIA Optima

Hi

Before you turn out the light you should have a code read carried out just to make sure nothing sinister is going on with the management system.

If the car is running ok then the code will probably either pertian to the O2 sensor, the EVAP system, or a drop in catalytic efficiency, but this isn't set in stone, just the most popular scenarios.

Very best regards

SOURCE: CAR WILL NOT START

Plug an OBD II code reader in and you will most likely see that it has an issue with either the timing belt or the crank position sensor. either of these will cause you to stall/not start. If timing belt jumped teeth or knock sensor failed the car will either run rough or not start at all.

SOURCE: 2004 KIA Optima LX timing belt/water pump

The thing is your doing the timing belt the water pump is right their with it . it should cost you much more at all besides the cost of the water pump. When doing a timing belt I have a rule that I go by The timing belt/seals =cam , crank , any pulley & tensioner & water pump all get replaced at the same time. I did a t-belt on a Audi A-8 very complex whole front of car has to come off as well, he didnt want to do w-pump & thermostat his thermostat was their as well not even a month later the water pump gave out he had to pay double the price because he didnt want to do it when I had it apart the first time. And make sure mechanic is ase certified . good luck

My 2004 Kia optima shut off will driving. It cranks but doesn't want to start up. Can any body help me?


Well , it's probably missing one of three thing's , spark , fuel or compression ! Now you need to find out which one , pull a spark plug wire an hold a screw driver in the end of the plug wire an hold it close to ground an have someone crank the engine over ! don't hold the screw driver by the metal , you don't won't to get zapped . If there is spark spray some carburetor cleaner into the engine at some point ,vacuum hose ,air intake , the throttle plate would be best , there is usually a black tube going from the air filter box to the engine ! A couple of clamps holds it on , take it off an the engine side you should be able to see the throttle plate ! If it tries to start after spraying carb. cleaner in , you have a fuel delivery problem ! Fuel pump relay , fuel pump driver module or the fuel pump it self is bad ! Now if you have spark an sprayed carb. cleaner an it did not try to start you need to check engine compression ! The timing belt may have worn enough for it to jump time a little causing it to be out of time ! Back in the 80's the little cogs on the belt would wear off an the cam shaft wouldn't turn . Back then it was easy to check by taking the distributor cap off a see if it would turn while cranking the engine !

Try to flush your transmission, and if that don't work you might have a bad band inside it or a syncro could be bad. The syncro is located on top of the transmission.

2004 KIA Optima, had A/C service now engine seems to been surging and fan go on and off. Can A/C be overfilled with R134?


Yes, the surging is caused by the ac compressor is turn on and turn off. I don't think the ac unit is overfilled but I'm fairly sure it the AC compressor relay or the sensor that run the AC relay is bad.

2001 Kia Magentis engine missfiring , installed


check new spark plugs for proper gap.
It may have gotten hit when installing it.check coils second for resistance/firing. sometimes one bank will work fine and the other side will misfire-always replace all together or as a unit. Check
engine for compression if problem pre existed
and check for low compression. if 1 cylinder
has 120 psi and two havepsi below 90 you may have
a cracked head or bad head gasket.
