Santa FE SM (2001-06) :: 2002 Starts Running Erratically Like A Misfire
Dec 12, 2012
My Santa Fe driving me crazy. Have a 2002 Santa Fe 4 cyl with a problem. It will start when cold and run normal about 2 minutes. Then it starts running erratically like a misfire. If you let it idle this way it will stall quickly and not restart until totally cold again the next day. If you catch it quick enough and continually pump the throttle it continues to run rough until it starts to warm up. As it warms up the engine slowly improves until it reaches operating temp. At this point the misfire is much less but still there. If you shut it off for more than 10 minutes it will not start until the next day. There are no codes at this time. I have changed the coolant temp. sensor, the cam position sensor, fuel pump and screen, spark plugs and wires. I have also verified all timing marks on the crank, cams, etc. The crank sensor was replaced about 40k ago when the timing belt was replaced. What can I look for now???

I have a 2002 Santa Fe 4 cyl that is giving me a problem that I could use some advice on tracking down & fixing . First & most important is a code P0302 # 2 Cyl misfire. How to check the ignition coil pack , injector ,& wire for this cylinder in home garage with normal tools & meter . Is there a you tube displaying how to do this step by step ?
The other problem which I don't have the code for at this time is that some part of the exhaust is not getting warm enough & this also put's the check engine light on . Will get back on this one when I solve the main problem Misfire.

High mileage santa fe 190K+ miles. Will only start while cranking. Dies when key is in "on" position. Fuel pump runs/cycles normally when turned to "on" position. No obvious vacuum leaks. No intake obstructions. Vehicle will cont to run using starting fluid. Vehicle starts, idles and runs (somewhat poorly) with MAF unplugged. Fuses appear ok (although the fuse cover/fuse index is lost). Stranded at rural property with limited tools and average abilities.

Those are the codes I'm getting. P0340, P1166 and P1167
Here's the story. Engine running flat under load. Easy acceleration is ok, but merging onto the turnpike causes a noticeable loss of power. Replaced the cam sensor, cleared the codes, ran ok for a day. Same codes came back, same flat performance.
Returned the cam sensor with another new one to make sure it wasn't a dud out of the box. Advance Auto Parts is awesome - replaced it no questions asked.
Installed the new cam sensor, cleared the codes. Ran great for a day, then the same symptoms came back, with the same codes. I'm thinking it might be the ECU? If it is, how expensive are they? And do they have to be programmed by the dealer?
This is a 2002 Santa Fe 2.7l automatic with around 147k miles on it.

02 v6 awd my power steering cooler had a leak and was spraying fluid all over radiator. I replaced it and did a coolant flush new thermostat and a new temp sensor. Was still getting hot gauge was touching bottom of red. Did some looking my ac wasn't working for some reason the fuse was loose. I pushed it in and the big fan instantly kicked on high along with the ac. The small fan on the front of the condenser isn't running. Could this be my problem? When is it supposed to be running? I swapped the relays around with no change. I might take it apart tomorrow and hardware fan to see if it shot craps.

My Treg starts to idle erratically. It feel as if it want to stall once every 30 seconds. Other than that it drives great. I talked to the dealer and they said that this is typical of VW's engine. It does not make sense. I did not experienced this when I first bought the car.

I recently replaced the transmission in my car. I put new oil pan gasket, valve cover gasket and plugs in it. Got everything back together and now it won't stay running. It starts but will not stay running . I pulled the plugs out to find they were the wring ones that a was sold So They gave me the correct ones. Still doing the same thing. I've checked every connection. All are plugged in all lines are hooked up.

I had a strange problem tonight, my car wouldn't start in park as it normally does, but did start in neutral? I certainly don't want it NOT to start! is there some sort of sensor that tells the car its in park and therefore allows it to start, which may have slipped/become faulty telling the car its safe to start, even though its in neutral and not park?

I am trying to fix my friend's 03 Santa Fe 2.7L with 325K miles on it. Pulled the codes and he has misfire in #3, 6 and a random one. It doesn't do it all the time, and when it does do it he can sometimes shut it off and restart it and it will be fine.
What is the likely culprit causing the misfires and how to test it? He can't just throw parts at it.

I have a 2001 Audi A4 1.8t (AWM engine, B5 platform). When I start the car, I get misfires on all cylinders (very rough idle, sometimes it stalls when the engine is cold) and the car appears to be running lean. Once the CEL comes on, it runs fine (albeit the slight loss of power do the ECU going into limp mode to correct the problem).
So far, I've done the following myself: new O2 sensors, new SAI pump, new EGR valve, new diverter valve, new N75 valve, new vacuum hoses, cleaned the throttle body, new MAF sensor, cleaned the air filter, new plugs, and new coils. When the problem persisted, I had my mechanic change the timing belt, check for vacuum leaks, change the valve cover gasket, replace the fuel pump and filter. None of this has solved the problem! This is driving me nuts.
At this point, there are only two possibilities that I can think of:
1) Catalytic converter is clogged? I pulled out the pre-cat O2 sensor, started the car, but it still misfired. This seems to mean that there's another problem (i.e., if the cat is clogged, it's in addition to something else).
2) Dirty fuel injectors? I've put two bottles of Techron through the car to no avail. From the outside, they look pretty dirty, so I'll definitely try removing them, cleaning them, and replacing the gaskets. Hopefully this solves it.
Is there something I'm missing?

This all started out when I wanted to change my original plugs that had 200k miles on them. I have that part done now and new wires. Then it wouldn't start without me starting it while holding the gas pedal down. Then I would have to press the pedal down or it would die.
I may need to clean the throttle body. I bought some Valvoline Throttle Body Cleaner and cleaned the throttle body it was black inside and now it's nice and clean. After that the car starts up fine except on the first try. It starts up and idles at around 2,000 rpms. When I press the brake it drops to 1,000, then back up to 2,000. The strangest part is I have no acceleration power now. I can press the pedal to the floor and it will only go to 3,000 rpms. It will slowly get faster as I drive but there's no immediate response when I press the pedal down.
Why would cleaning the throttle body do this? It throws a code when I first start it and it dies the P1110 code but I think that is because the rpms are at 600 when it catches it. No misfire codes or anything, so I think the plugs and wires are working. Just the faster than normal idle now and no power when I press the pedal down.
Would the throttle body cleaner hurt the throttle position sensor?

We just replaced the starter on a 2004 Hyundai Santa fe 3.5. The car now starts, but won't idle. I can keep my foot on the gas and keep it running, but as soon as I let my foot off the gas it dies. We didn't have this problem before replacing the starter. Where to start looking?

My car has the same issue, its a 2001 santa 2.4 . Its starts and then shut off after 3 seconds. camshaft was replaced twice already. still same issue, die after 3 seconds. everything seems to be fine.
What about fuel pressure at the rails? If the pump runs for a moment when the key is turned to the on position then when cranking it stops. That would let the engine start and run for about three seconds. Could it be the ignition switch?

2002 Hyundai Santa Fe 2wd 2.7L 175,000 miles
Having misfire in #1 &4, new plugs, new wires, new coils, new cam and crank sensors, cleaned and tested fuel injectors, checked injector signal, checked timing belt.
Swapped around plugs, wires and injectors(keeping same firing order) and the # 1 & 4 will not fire. There is spark to the wires and plugs and gas thru injectors but no detonation.
With plenum and exhaust manifold removed (front only) visually checked valves. Installed new oxygen sensors while exhaust was out. Tested ecu fuses in black relay box in engine compartment.
Engine stars first time ,every time but only runs on 4 cylinders. Check engine light code reads no 4 cylinder misfire.

i have a 2001 elantra with 136k. the automatic transmission (which otherwise shifts very smoothly and shows no sign of problems) shifts suddenly and erratically when i'm driving at a constant speed. I'll be traveling along (speed doesn't matter), and it will suddenly downshift, then upshift, then downshift, etc. this started off being very occasional, but now it randomly shifts every 5-10 seconds.
I've changed and checked the fluid, and tried replacing the Input Speed Sensor and the Output Speed sensor...that didn't fix it. it also does not blow a check engine code. I'm convinced there must be a sensor somewhere that is faulty. it really seems as though the transmission is electronically confused.

New battery installed a few weeks ago - 120k on 2001 Silverado. When it is rainy out, the gauge acts erratically (yesterday the needle was between 14 and 19, today it is between 9 and 14 and the battery light is on. What can I check to figure out what might be happening?

I just purchased a 2005 Santa Fe, 4WD, 2.7l..the engine has a miss...the code that came up was "misfire in #2 cylinder"..I checked the coil pack...and the wire harness just crumbled..so I replaced the coil pack...reset the code..and it was good for a couple of days...I got through inspection...today I put on the A/C..and the engine got rough..the check engine light came back on..same code..misfire in #2..I'm thinking the injector or what else could it be? plug? wire?

I just felt that my 2005 Santa fe shakes when idle in front of a traffic light today, later on the check engine light illuminated. Drove to a Monro shop right way and diagnosis using their professional OBD reader, it turns out that the Cylinder 3 and Cylinder 6 are misfiring according to the OBD scan result.

I have a 2004 Santa Fe with the 3.5. Today I started it and the check engine light came on. It was not on before this. (We had a lot of wind and rain from the storm but nothing major.) And seems to be running fine. I went to the auto parts store and they ran a diagnostic and the Code P0306 came up #6 cylinder misfire. They said probably Spark plug, wire or coil for #6, then went to look up code in computer and did not have my truck so they went with Kia or Domestic, which gave different possibilities for a code P0306.
They had me buy some fuel injector cleaner as injector was on the list. The light is still on so I guess the cleaner was not the magic bullet. I spoke to a lady at another auto parts store who is a wiz when it comes to cars and has been around them and fixing them a really long time. She says the Code P0306 is Spark Plug, wire, coil #6. She has a 4cyl Hyundai car not truck and she had the code for her #4 misfire in the past and she started her repair cheapest first, Plugs, wires her code was still there she then changed the coil and that did the trick for her.
I on the other hand can't do this stuff myself. Can't afford the dealer anymore or to have a shop do a tune up AND coil if I don't need all new plugs and wires just a coil as they will charge a lot to do a lot all. And it may not need it or even be any of those things. I also suspect the dealer and shops will want to still hook up their computers to do an costly diagnostic because the light is on, even though I know the parts store already came up with a code P0306 twice. Spoke to the dealer on the phone and he already basically said they would want to do that first for $100 plus the cost of repair.
I brought the truck new. It now has 91,500 miles on it and the dealer has already done two tuneups on it in that time, Plugs and wires. I hear it probably shouldn't have even needed these tuneups in this amount of millage? So the last one was probably about 2 years ago and a few thousand miles maybe a guess 10,000-20,000 miles ago. Do you think a plug and wire would be bad already in that few miles?

I got a check engine light. I went to Auto zone to get it read & they came up with a P0303 - Cylinder 3 misfire. Since I bought the vehicle a couple of months ago, I don't know when the plugs were last changed, so I decided to change them. However . . .
Is there a secret to getting the plug boots & wires out of the hole and off the plug without wrecking the wires?
