I have been having problems with my 2003 Santa Fe (4cyl, 2.4L) dying out of the blue. I can be driving for 20 miles and it's fine, then all of a sudden the RPM's are erratic and I lose power. Any thoughts on what it could be? Help!!!
Your description of the problem is vague. Vibrations? Noise? Could be a lot of things, but a bad ignition woudl cause a problem throughout the whole powerband, no? Sounds almost like a fuel problem to me personally.
It should be covered by your warranty, unless you drive A LOT.
P.S. Any Check Engine Lights posted or other hazard warnings on the dash?
Thanks for the welcome. The check engine light is on (no noise or vibration) and I have had it hooked to the machine and it just indicates ignition coil primary/secondary malfunction (P0350). But with their being two it doesn't say which one. Is there a way to determine which one is bad and not waste money on both? Oh, and I have about 85,000 miles on it so warranty is out. Thanks!
It has the check engine light and you can't determine the problem until after you drive for about 20 minutes. It runs fine after you get it up to 50, but you have to do so verrrrry slowly because it's not wanting to accellerate. I had it hooked to the machine this weekend and it said ignition coil, primary/secondary coil malfunction (P0350). Any ideas on how to determine which coil is bad? There isn't any vibration or noise, just stops wanting to accellerate from stop and then tries to stall if you don't keep your foot on the accellerator. It also has about 85000 miles on it, so no warranty for me. Thanks in advance for any help!
I'm new here so do not know all the threads. I'm sorry, I thought the Santa Fe was the right forum. Still, 200 reads seems to be pretty used to me. But thanks for your suggestions and making a new member feel welcome and not chastised.
I would like to thank the members who did respond. Thanks. I will try checking the coil resistance and burn tonight.
did you find out which coil had the problem? I am running into exactly the same symptoms as you and don't know which coil it is. Actually, where are these coils? Do you have a picture of them? Thanks.
I finally changed one of the ignition coils on the hyundai santa fe (4cyl). Before that the mechanic had recently replaced the timing belt. The idling is much better and it doesn't feel like it is going to stall. However when idling it still feels rough, even after warming up. Do you think it might have to change both coils? I just changed the one that smelled like burnt plastic. Maybe the specs of the new coil do not match the one I didn't change? Would that be causing this problem? Or it may be related to the timing belt that was replaced?
