car acts and sounds as though it is not recieving fuel. checked the fuel line coming off of fuel rail and pump works properly. checked all spark plugs and can see noticable spark from 4 of the 6 plugs would this cause the car not to start? what else can i check?
shift I shut the engine off and started again it still was locked in park I kept pushing down and finally I could shift to drive. This has happened twice in the pass two months. I have 138000 miles. I"m due for automatic transaxlefluid and manual transmission fluid. Thanks for your input
they ate staying on constantly... and my cruise control will not set!!
While im driving, i get up to 30mph and the car begins to shake. I let go of the gas pedal slowly and it stops. Sometimes it shakes really bad sometimes it shakes just a little. The shaking seems like its coming from the front drivers side. I switched the tire to the back and its still the same. I already checked the balance of the tires and they are fine. What could it be?
I would put my car on cruise and it'll start acting funny at times. Its starts off by speeding up (ex: cruise is set at 60mph, and speeds up to 61 then lay off the gas and repeats). Then itll turn the cruise off on the dash (not the on/off cruise). Then once you get it back on cruise, it goes on high rpms for about a 1/4 of a mile at 60 mph. My speedometer drops sometimes 10 mph less than the speed limit it was on or goes straight to zero for about 150-200 yrds. All of this happens randomly, nothing changes if I have 90 degree heat, 62 degree A/C, or with the windows rolled down. It does have sports mode but I haven't used it and it is a used vehicle. The previous owner was also having problems with it. Took it to the shop and the mechanics there couldn't find the problem, nor was it throwing any codes (still not throwing codes).
where can an evap control system pressure sensor high be purchased
I had my car serviced recently and my mechanic informed me of the condition of the sub frame. Its rotted out pretty bad. Im not sure if its gotten worse since the recall work was done. He suggests replacing the sub frame. Is this an expensive job and do I need to replace it considering the recall work was done.
It vibrates worse when its cold and in drive . But not in neutral and now its making transmission slip sometimes. Could it be timing belt tensioner?
my car will not crank sometimes ,maybe weeks and it does it again had it towed and it was the sensor harness ,but can not find the part please help
Does the alternator belt have to be a 04 Kia optima for the car so start? Everything has been done to this car and it's not a chip in the key problem and it still want start, no codes will show when I run a diagnostic test. Thanks
Can someone tell me about my 2004 Kia Optima LX? It is getting fire & fuel, replaced crank sensor and timing belt, plugs & wires are good and the car still want start any suggestions? Thanks

This vehicle was purchased from a family member and this is the second time it's done this. The first time they took car back and apparently put in New alternator and battery. This time vehicle stopped running while driving on why 17. The vehicle was towed and when the key is turned the lights and electric comes on but it won't start. How do I troubleshoot and find out what this could be.
Runs and starts fine after driving for awhile it slows down till it comes to a halt. After letting it cool down it will run normal for another while. Had the transmission oil changed still the same what can it be
