Question about 2003 Kia Sorento

1 Answer

My car's motor seems like it is surging. I especially notice it when going between 35-50 miles an hour. Was low on fuel before snow, filled up on Monday, car ran fine until Wednesday. It has been extremely cold here. Could it be water in the gas tank or maybe the EGR Valve. No check engine lights nor any other warning lights have come on. Any idea of what is going on. Car really running bad now after trying to go blow it out.

It could be many things, even if the check engine light is not on, the computer should be scanned to check operating systems to pin point the problem, it could be as simple as a coil. or a weak fuel pump. have it scaned, auto zone scans for free. hope this helps.

Engine Surges after gas fill-up

Your EGR valve is dirty - or has failed.

You can try to glean it with EGR cleaner - however 99% of the time it needs replacement.

Do you notice does the problem seem to worsen in rain or humid weather? Try checking the MAF sensor it may just need to cleaned it can cause problems like this. Be sure to use MAF cleaner nothing else. The sensor may also be bad but try cleaning it first, its cheap and only takes about ten minutes.

I ran low on gas in my 2004 toyota solara after filling it up i noticed that it lost power and would'nt go over 45 miles per hour....what do you think the proplem could be?

There are always deposits inside the fuel tank. Usually, driving around with more than 1/4 tank slshes them around enough to keep them out of the fuel pump screen. But, when you run low on gas, the sediment gets sucked to the screen, and blocks your fuel flow. If the solara is built like most toyota cars, there will be an overhead access to the tank. This is located under the rear seat bottom. Remove the rear seat bottom by pulling up on the back of it first. then tilt the rear toward you and push the front of the seat about 1/4 inch backwards. This will disengage the front clips of the seat. there will be a little circular cover with 10 or 12 bolts under there. remove the bolts and lift the cover. Pull the assembly out. You have the fuel level and pump assembly in your hands. At the bottom is a little motor and a fine mesh screen. When clean, this screen is white. When dirty, its usually a brown-orange color. You can get this screen from autozone or advance.

I would first check the fuel filter to see if it is clogged. If that is good, test the fuel pump to see if it is working properly. Next check the fuel injectors are not clogged.

P0300 Random Misfire

Misfires can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.

A Random Misfire code usually indicates a vacuum leak or bad gas.

NOTE: If a misfire in a specific cylinder should lead you to check the spark plug, fuel injector and compression.

Getting way less milage after fuel was replaced : HELP

First off,If the mechanic didn't have the pump in his hand when you met,Have the car towed to his shop right then and go into work early,He didn't put a new one in and have your car back in 2 hours (since the pump is located inside the fuel tank and the tank must be removed to get to it and)

Not saying it can't be done in 2 hours,if all the tools,parts,and ducks are in a row waiting for you.

Secondly,Additives are great until you over use them,mix and match them,Etc.....

To the search questions
#1 The filter should have been changed with the pump or at least at the same time.
#2 The fuel pressure should have been tested by the mechanic after installing the new pump.
#3 If you have a vacuum leak,the car will run rough or at a higher or lower idle.

Try a good tune up.The additives have probably fowled the plugs and may even destroyed the injector seals inside.
