Engine Performance problem
2001 Kia Optima 4 cyl Front Wheel Drive Automatic 58450 miles
I had maintenance done on my car at 50,000 miles and ever since, whenever it is humid outside and my car has been sitting all day or all night, it stutters and almost stops running when I start it. It does smooth out after it warms up - usually about 10 to 15 minutes if I just sit & let it run. If I try to drive while it is still stuttering, I have one heck of a time getting it to move. Generally, if I can keep the RPM's at 2k, it runs smoothly.
I have taken it to the dealer (who did the maintenance) 3 different times, but they have not been able to find the problem.
Can you give any suggestiosn as to what could be causing this? My friend thinks it may be the spark plug wires and I'm inclined to agree but without knowing a lot about cars, I just don't know.
Thanks for any info you can provide.
have the same problem?
