I am wondering if anybody has this type of problem. Firstly I got a lot of maitenace work done on my sante fe (timing belt trans flush, fluid change in transfer and rear end, steering flush and hose replacement, and rear end seal replacement valve cover gaskets also) This situation only comes with the engine warm, usally the tach reads 750 when idling. Now hen i drive no problems but when I stop, the tach guage shows a sllight drop then it drops to the 250 mark and almost stalls out then it goes back to the 750 mark. I have taken it back to the dealer to tell them but nothing that they could find (twice) the techs have seen the guage go down but nothing, they said I will have to leave it all day to find the problem. The last time they had two techs for a couple of hours and still no fix.They also said that they reprogramed the computer for rough idling but no solution yet. Anybody have any ideas for me to look at.

Thanks
Roman

Do the headlights dim when this happens? You might have a voltage drop problem due to dirty battery cables. There is a TSB

Reach up behind the starter and find the Crank Position Sensor pigtail at the sensor body... roll it between your forefinger and thumb..

Is the jacket all cracked and crumbling ??

Yes... feel the wires inside with thier jackets all crumbled..

Yes.... replace the crank position sensor... them 3 wires inside is shorting on you and PCM not know where crank is.

just got mine back...same problem for weeks no code.. It was the crank shaft position sensor.. completely failed-- car stalled like crazy and slipped cold or hot.... There is an open recall on this defective part. Dealer said my vin number did not make the recall. My mechanic said it was the part as it was the original part. It was change yesterday problem 100% resolved... Even if you dont have a code for this, this part may break either way.

2004 Santa Fe 2.7: I don't know if my problem is the same. About 6 months ago the car started OCCASIONALLY hesitating and skipping, even while driving on the hwy! I would push the gas pedal and it sounds like the engine is revving, but no speed. Sooo, mechanic changed the fuel filter (60,000+ miles, needed to be done anyway.) OK for a week or two, then it started again! Mechanic read the error code and determined it was the camshaft sensor. Replaced the sensor. Worked great for a short while then.....here we go again! Less than 1 month ago we took it to a different mechanic, said it was the fuel pump. Changed the pump. Thought it was fixed until a few days ago and it's still skipping and sometimes the engine just quits! What's so frustrating is this doesn't happen all the time. Drove 20 miles the other day, no problem. Drove 5 miles yesterday and I barely made it home when the engine quit. I love my car but I'm ready to pull my hair out over this. It's already cost me over $600 and I still have the problem. The mechanics are trying their best, but at this point I feel they're guessing. Ok, you professional or backyard mechanics out there! Please HELP!

Your help lies within post #5 and Post #7 above.. wait till engine is cold, as you have to slide your arm right beside the exhaust manifold/catalyst and behind the starter to reach in there..

I kind of have the same issue on a 2.4. It likes to skip, I guess that would be the term, not all the time but most times. Also it has been gettin more noticable at speed.
