#1930 of 1938 2004 Santa Fe 2.7L V6 Misfiring
Feb 21, 2013 (6:35 am)
As you can tell from the title, I have a 2004 2.7L V6 Santa Fe with around 124,000miles. I recently had it at the dealership for a tuneup and because the check engine light came on. The code was P0303, meaning its misfiring in the 3rd cylinder. I had the spark plugs, wires, and coil packs replaced. Originally, the compression in the 3rd cylinder was not good but after having all this work done and having the gasket checked, compression came back good. The issue is I am still having misfires in that cylinder but not steady misfires. I started and drove the car for about 30mins with no problems while sitting in stop and go traffic but then it started misfiring again. The mechanic at the dealership said it could be the timing belt, which I had replaced at 98,000miles because the crankshaft pulley is wobbly but that he would have to open it up to see. I have seen some posts in the past about this same issue and was wondering if anyone had this problem more recently and what the cause was? If it is the timing, why would only 1 cylinder be having the issue?

Since Dec 2012 my Santa Fe 2004 3.5 has been in the shop about 5 times tune up was done purge valve replaced plugs wires and coils replaced and catalytic converters bank 1&2 and some $600.00 pipe that apparently goes to the exhaust as well every time I get it back I drive it not even 500 miles and then the car starts not wanting to accelerate and hesitates and jerking like turbulence in a airplane (a new transmission was put in 2008) When all this started I thought it was my transmission which they checked and said that was not it. Its back in the shop now they think it may be my timing belt I have put over 3000.00 since this all began and I just really need some ideas as to what causes these misfires just want the problem fixed I cant afford another car and someone else's problems just want to fix the one I have I don't know how much longer I can afford this Please help someone

I have a 2002, 4 burner Hyundai Santa Fe. I was driving my Santa Fe for about 50 miles when all of a sudden it started acting weird. The RPM's went between 3,500-1,000, it felt like I was hitting turbulence, and then it died. My first thought was the fuel filter, so I replaced that. It ran for about 10 miles, and started acting up again. My next thought was the fuel pump, so I replaced that, and that didn't solve the problem. When I turn the key to on, I notice that the pump turns on, but I unhooked the cables to see if it was actually pumping fuel, and it wasn't. I then turned the key over, without pushing the clutch in to see what happened. It started pumping fuel at that point. I have found that if I turn the key over before trying and actually turning the car on, when I do go to start it, it will start and run for about two minutes, before it starts to act up. I cannot get it to stay on long enough to drive it even mile. It has about 130,000 miles on it. I hooked up a diagnostic reader, and it threw four codes.
1. Camshaft positioning sensor
2. Crankshaft positioning sensor
3. MAF or VAF low input
4. MAF or VAF low input
I need help with this problem, and my dad mentioned that I put the problems up on a forum. If you have any idea what it might be, I am open to all suggestions.

check for leaks along the intake tube - if you can't hear or see any - spray around it with intake cleaner/throttle cleaner/starter fluid while it is running - the engine should respond to the into of the cleaner and change rpm - that is where the leak is if there is any - I am assuming the filter/maf sensor/throttle is clean...

does this only happen with the a/c on?

I have charged the A/C, but it continues to blow cool air, not cold. Could this be the "evaporator?"

Did you ever receive a reply on this? I've got the same problem.
#1937 of 1938 Santa Fe 2007 fuel sensors
Oct 30, 2013 (5:31 am)
Well, you can add my name to the long list of frustated Santa Fe 2007 owners because of faulty fuel sensors. Just like some other lucky winners both fuel sensors failed at 75,000 miles. About $600 if I go back to the dealer or $220 if I want to give it a shot. So instead I will use my OBD scanner once in awhile to check for new codes and make sure I fill up the tank every 250 miles or so. By the way my rear brakes froze and I had to replace everything (rotors, pads, drums). Another common issue on the Santa Fe 2007. Other than that it is a good car
