Santa FE SM (2001-06) :: 2.4L Engine Running Rough / Rich Smell All The Time
Dec 7, 2012
When firing up the engine cold it runs really rough, smells very rich all the time, even warmed up. No codes set, fuel trims are within 5-10%. I've replaced the front O2 sensor, swapped crank & cam sensors, Map sensor (have lots of spare parts) & I'm sure there was more things I've changed but can't remember. I have a snap on scanner and everything is within parameters.
I have not checked the EGR valve or solenoids yet. It's a 2006 Santa Fe 2.4l 5 speed, new timing belt & balance belt replaced when I dropped this engine in. Is there a common problem with these that I could begin looking for?

Recently replaced plugs/wires on soon-to-be 10 year old '04 SF 3.5L (157K mi.) for the first time.
Plugs were OE Champion Platinum and all 6 looked identical except for excessive gap of .010 +/- due to all the miles. Replaced plugs with same as OE. Old plug wires looked good, but replaced them with aftermarket wires ( fit was as good as OE). Also replaced plenum gasket.
Problem is: engine runs rough at idle and high rpm and appears to be mis-firing. CEL is off and code reader shows no Trouble Codes stored.

I recently replaced timing belt and balance belt on my 2004 santa fe 2.4l and now the engine runs like crap and shakes badly. I went over all timing marks again and again and I am at a loss.

1994 reg cab 4.ol 13ok.. my wife just got it, been doing some small things like replaced dome light, replaced cargo/third brake light, truck starts and seems to run ok. but i get a headache in it which i believe is carbon monoxide, has a leak or something? i text previous owner, he said he replaced 02 sensors, but didnt say if they were bosch or a good brand.. also trucks has a oil pressure and coolant temp gauge fitted on by the gear shift as the dash gauges for those functions are out. Does this mean the CTS may not be working and affecting fuel/air I do not know these trucks i only just found out what this strange silver looking thing was it is the IAC, I Believe, then there is this black plastic vacuum type cylinder by the passenger side firewall, what is that? and right against the drivers side fire wall is a small reservoir type thingy, is this something to do with ABS? i do have an ABS light on, was hoping it was the bulb out on the third brake light or something quirky like that no such luck its still on after starting engine. but i am concerned about this running rich/strong smell as we really cant take it far as is it, its dangerous, may have to get a smoke test? Just got the truck, trying to get caught up..

I recently (in the last few months) have noticed my truck (1999 F350 duallie) seeming to be running very rich … I pull a 32' trailer with it and noticed on the art few trips the front and right side of the trailer covered with diesel fuel spots when I got home …. It also smells very rich when idling…. The last couple times I started it in the mornings it seems to crank a very long time before it starts …it still runs but its got issues evidently … it has these 3 codes :
P1280
P0475
P1670
The 1670 will clear , but the other 2 I can't clear, they are right back every time you turn the key on …

My 2001 Toyota Celica GT was put through a smog test and it was running rich on the idle only. It has been tagged a gross polluter and so i finally got a code reader to try to diagnose why. When i plugged in the code reader it kept stating no codes. It does not have a check engine light on and has not had a tune up for a while now. I am in real need of my car now more than ever.

Well today I have moved on to the next project on my 02 v6 4X4 Santa Fe, which is the rough running. When I got the car, it had CEL with codes for misfire #5 and lean condition codes. I noticed the wires were in need of replacement (one had black tape wrapped around it) so changed the plugs and wires. The 2 hoses, one that goes between the valve covers on the pass side and the hose between the valve cover and throttle body on driver side were both cracked so replaced them along with a few other vacuum lines, just because I had access to them. Cleared the codes and it still runs like crap, but after 112 miles, town and highway driving, there are no CEL codes. When its first started it idles at 1500 and sounds like its missing and has very little power going down the road. When it warms up seems to run a bit better but still nowhere close to what it should. Equal compression on all 6 cylinders and has power to all 6 injectors and tested to be sure there was a pulse to them as well. Coil packs all tested well. the exhaust is in bad shape and don't know if that would have any effect on how its running.

2001 Santa Fe with 2.4 engine auto FWD 198k miles. When it is started first in the day, the engine sounds good and shifts well. After a few minutes and also after stops, first gear works well but then the following gears do not work well almost as if the engine and the transmission quit talking to each other. Traveling at 60 mph starting up a medium hill, the car downshifted and could not pick a gear. Although I pushed the pedal harder, the car did not respond rather continued to slow down. It acts like I lose 2 of the 4 cylinders in all cases. I replaced the spark plugs and two of them had oil on top of the plugs and also all around the threads. I replaced both coils thinking that one of them was the issue but no change has been observed. I replaced the throttle position sensor; no performance change. I do not believe it is the transmission as I have not notice any clunking, or bad shifting when starting out. While coasting at 40 mph in neutral and my pedal pressed at a certain position, the rpm gauge fluctuated from 3k to 3.6k many times for the duration of 20 seconds.

My 03 Sante Fe is running a little rough and is stalling. My Mechanic said this P code was going to run me $1300. I'm not very mechanical , but this just seems very high. He said that aftermarket sensors would not work and only Hundai parts for the fix.........

My engine is running rich, flooding? My truck is a 1986 F-150 302 EFI. The engine idles rough, black smoke and soot comes out the exhaust pipes, and black soot on spark plugs. Symptoms seem to disappear if I throttle the engine and hold it, but as soon as I release the throttle the symptoms reappear and in most case causes the engine to die. These symptoms have just started a week ago. What the problem is.
Fuel injectors are cleaned and rebuilt. New plugs and wires. All new fuel pumps and filters. New air filters. New fuel pressure regulator. New dual function reservoir. New 3-piece timing set. New O2 sensor. New EGR Valve and sensor. New idle air control valve. New distributor, cap, and rotor. New ignition coil. New high volume oil pump. New alternator. New pcv valve. New knock sensor and air charge temp. sensor.

I just had my check engine light come on and checked the codes and they were P1136 running rich at idle and P1250 low fuel level. My fuel level is 3/4 full and I just installed a K&N panel filter in the airbox. While I was installing the filter I also cleaned the mass airfow sensor and then cleared the codes. The codes have come back after 2 days.

I have an 07 with the 3.3L and on start up the engine runs really rough and while driving when warm it keeps losing power with a regular rhythm. It almost feels like and injector or ign coil is dropping out. I have no CEL and have recently changed the spark plugs and rear upper O2 sensor.

I was driving around running errands when my AC stopped blowing cool air, a funny kind of "metallic" burning smell was coming from the engine, and there was a slight knocking noise that was apparently coming from the engine and would go faster as I accelerated.
My car is still under warranty so I know stuff will be covered. My question is : what the heck is going on with my Santa Fe? I need to know whether I should call into work or drive it anyways.

This little engine runs very hot. To make matters worst the radiator fan comes on high on the gauge temperature reading unlike other cars I have had in the past. What else to do to run the engine cooler without affecting fuel economy? I wish there was a way to make the radiator fan come on at a lower temperature.

I have a 2002 SantaFe, V6 DOHC 4 dr, 117000 miles, that I bought in 2002 with 12000 miles on it. A couple days ago, I smelled an electrical burn smell coming in my interior air vents (no smoke).
From the top rear of the engine, closest to the firewall, was about a 6 inch wide plum of white/gray smoke, just enough to see through. I looked under the car and there wasn't smoke coming out underneath ( no wind that day). No Warning lights, engine light, etc.
I have always taken car of my SantaFe, Bud, regular oils changes, trans oil, air pressure, etc.
Since about 2007, during a couple of oil changes I have been told that there was an oil leak on the top of the engine, probably a gasket. I figured since there were not spots on my drive and it never needed topping off before the next oil chng, I would keep my money for the other bills.
What can cause smoking like this considering where it looks like its coming from? Could it be from more oil pooling over time? Can engine oil smell like "electrical" burning smell?

I have a 2002 Santa Fe V6. I'm getting the codes p1529, p0755, p0760, & p0765.
The car can start up & go, only for a short time. Engine will keep running, car won't move.
Kill the engine for 3 to 5 minutes, can start it up & go once again. Going 40mph increases the odds of the car not moving quicker.

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.

The headlight beam height can be adjusted from inside the car. But even when not fiddling with the dial, I hear an electric motor sounding noise from them time to time, just a short <1s whirring sound. I listen with the bonnet open and I'm pretty sure it's coming from the headlights. Is this normal? is there any way I can stop it?
