I have a 2005 Kia Optima that is acting up. The car is a 2.4 L 4 cyl. automatic with 101 thousand miles on the clock. For the past couple of months, maybe once or twice a week, the car would hesitate on acceleration. A couple of jerks as if it was chocking and it would keep rolling as if nothing happened. The past week has been frustrating. The car would start to hesitate and a few seconds later it would die. Yesterday, the car died in the middle of a busy street during peak hour traffic. I had no choice but to hit the hazards and sit it out. After a few tries to crank the car it finally started again and I was able to make it to work. On the ride home the same thing happened. This time I had enough momentum to coast onto a side street and park out of the way of traffic. After 30 minutes of periodic attempts to start the car it suddenly fired right up. I am not sure what it could be but this is what I plan on doing tomorrow: Replace fuel filter, pcv valve, spark plugs, wires and air filter. I may be shooting in the dark here bur I admit that the car has never had a tune up or a fuel filter changed. Does anyone have any other ideas? Thanks in advance, Pete | ||

welllll Is there a check engine light on? If so take it to Autozone they do free light checks. If not it sounds like a fuel delivery problem. Almost like the fuel pump is cutting out OR the connection is loose... | ||
| Joshinga |
+1 spidy it sounds like a dinosaur juice problem or the lack there of. | ||
| Piotr12 |
Yes, (forgot to mention that) the check engine light is on. However, it has been on for a LOONG time! The code is P0320 (engine speed input malfunction) One day my tachometer stopped working and illuminated the check engine light. | ||

Well go to AZ and see if they can pull a history to see if the fuel pump is coming up at all... | ||

My Ford Windstar was doing the same thing. My husband changed the plugs and wires. No luck. So he replaced the battery. No luck. So he changed out the alternator. No luck. Now he thinks it may be the "electric relay"? We haven't found the problem yet... but I don't recommend changing the expensive battery and alternator unless you're sure that's what's needed. Because after all the money we've spent...it still has the same problem. Not much help...sorry | ||

Air, fuel, spark. Got air, it's either fuel or spark. Looks like the 2001 Kias have issues with the CKP Capacitor or the wiring for the throttle position sensor.

I had a neighbors car acting the same way, turned out to be a flakey fuel pressure regulator. Real odd as they usually just fail, this one decided to play games.. Easy fix once I found it. | ||

Jeremy, Didn't the original post say it's a 4 cylinder? Does the V6 recall apply to this? Mine is a V6 Ford, I wonder if the same problem as the recall applies to me? HMmmmm.... | ||

Long ago had a problem w/ similar symptoms - Started fine, ran fine then for no reason would run like a dog for awhile and stop. - If you waited awhile would start & run fine again Did too many things to list here - found the problem - crap floating around in the tank | ||
| Ft_bstrd |
Doh, missed that. | ||
| Mindi |
 Dear God, I'm laughing so hard I can't breath. I never thought to look for "crap floating around in the tank". I can't wait to tell my husband that is his project tomorrow. Supposed to be sunny and 70 degrees tomorrow, who thinks he's going to be looking for crap in my tank????? I'm dying here. | ||

Sometimes when the Crank and/or Camshaft position sensors get hot they'll act up. It will happen more frequently as the sensor gets older. They're pretty easy to install, took me 5 minutes to do on my wife's Saturn Vue. | ||

That is a common symptom for a clogged fuel filter or "sock" on the pickup tube in the tank. It sucks all of the fuel it can until things plug solid then it quits running. When it is not running the suction pressure holding the "crap" in the flow path settles back out. When you start it up it begins to pull the same "crap" back into the same place, ergo the run quit cycle. But it could be electrical also. | ||

Call Click and Clack tomorrow morning!  I agree with some post above. Sounds like a fuel problem. I think you are on the right track with the things your going to change. I bet that solves it! | ||
| Mr_grumpy |
What Vern said, The first thing I'd be checking is fuel delivery. If it's not had a fuel filter (or any other love) in a long time I'd reckon on that being first call. | ||

Fuel or electrical glitch. Modern electronics just get weird & die and you don't "fix" them you just replace modules. This has led to people forgetting that sometimes it's the wires between black boxes that break...... The above advice sounds good, check the code, change the fuel filter. | ||

DTC P0302 = OBD-II #2 cylinder misfire. It's not likely a fuel problem, except the injector, if there are no other misfire DTCs. Misfire DTCs range is P0301~P0304. Fuel filters on modern F.I. engines do not require replacement until the fuel pressure drops below spec. So, check the fuel pressure before spending $ on a filter. With a #2 misfire; a spark plug would be a good start. But it could be the injector, or its connections. If you don't have a service manual, strongly suggest that one is obtained. | ||

A tuneup DEFINITELY won't hurt. If the tune doesn't make it happy again, take a look at / clean the throttle body with some carb cleaner spray. You could have stuff gunked up in there - TPS, AIS. My bet, though, with 101k....tuneup. Plug wire is probably shorted (look for a brown area on the boot - that indicates a short / arc to ground where the ignition pulse is not making it to the plug electrode, but is taking the short route to the head). | ||

Last night I was able to change the spark plugs and wires. I replaced the PCV valve and air filter. Today I will replace the fuel filter and check the sock at the fuel pump as suggested. I am going to risk it and drive to Auto Zone this morning. Hopefully they can pull some codes that will help me out. Thanks everyone for your suggestions. | ||

replace the Fuel Filter.... | ||

A clogged fuel tank vent can cause the symptoms you described. G | ||
| Piotr12 |
Stuck in the side of the road. Car won't start. I was able to get a code at Auto Zone. It is P0338. Crankshaft position sensor. Now of the Towtruck would hurry up! | ||
| Damnut |
Like I mentioned, glad you finally found it. Unfortunately & typically, breaking down on the side of the road is how that problem is found | ||
| Damnut |
You can probably change it right on the side of the road. | ||

That's the one that went on my Caravan. They go to silicon heaven. http://en.wikipedia.org/wiki/Silicon_Heaven | ||

Welp, the sensor will not be an easy fix. The motor has to come out to get to the crankshaft end of the harness. What a PITA. |
