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

Geordie

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

Don't think changing either the belt or the alternation would cause those changes. You must have moved or damaged something else in the process. Just what, I have no clue.

Sound like you either had to disconnect a wire to get out of the way when you removed the altinator and didn't reconnect or you knocked one off go back and check your work.

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.

My 04 Kia Optima will start but then it runs rough. It acts like I might have trash or water in my fuel line. Does anyone know where the fuel line filter is located, also could this be a problem with fuel...


Put a can of a product called "Seafoam" in the gas tank. Also do the following procedure.

Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Is the car flashing any codes. I would look for fuel issues possibly fuel filter, injectors etc. Because these items are easier to check. Otherwise it sounds as if the timing is off on the car. If the Hydraulic tensioner is not replaced this could cause the belt to jump teeth as well. PRETTY SURE YOUR TIMING IS STILL OFF
