I wouldn't worry about it unless you see this happening regularly over a period of time. If you got a bad batch of gas, or something along those lines, it could've caused it to happen. If it hasn't happened again, and you have no check-engine light and your fuel economy is where it usually is, I'd chalk it up to a random occurrence and not worry about it. If it starts happening more, try and note as many things as you can about the situation (ie, how long it sat, how much gas in the tank, is the engine warm or cold at startup, any recent maintenance or repairs, etc) - all of that can help a diagnosis.

Choke light won't go off in my 1985 El Co


What happens if you unplug the choke ? And the oil pressure switch?
On some models the oil pressure switch activates a relay for the choke heater. On other models the choke light acts as a check engine light for the very basic engine computer.

Almost no acceleration engine will not top 2K RPM under load.


Have you checked the air inlet sensor on the air filter. If this fails the engine goes into safety mode which it seems has happened. I don't know the specifics of the Santa fe but this is a feature of most modern electronic engine systems.

Car pulses and rpm fluctuates what is it?


if the car is running does it have the check engine light on? if yes what is the code if no then check to see if temp sensor is reading the right temp by plugging in a scanner that can read all data to give you an accurate reading... if it reads wrong temp it can cause running issues

Just picked up a truck 2000 s-10 everything checks out with this truck except for at about 40-50 mph hour it feels like its being held back sometimes. it just very sight enough for you to notice jerks...


The oil pressure is supposed to increase when accelerating and come back down when idling. Try replacing the fuel filter and see what happens but the oil pressure has nothing to do with it.

I have a 2005 Chevy Uplander, and when driving on the highway at about 60-65, the van occasionally drops RPM's and when you press the gas harder, it recovers without any jerking or anything. The same...


This is a rare one and can be tricky. Since your rpm gauge rises back up when you increase your acceleration slightly but you feel no jerking of acceleration then this tells me that a speed/rpm senser either has a bad connecton or the sensor itself is going bad when the engine reaches an optimum heat while driveing on the highway. Since you feel no acceleration when you slightly press the accelerator down but yet the rpm gauge is increasing back to normal, the throttle body sensor may be compensating for the failed speed sensor/failed sensor connector. Please get your uplander diagnosed properly first to confim this.

Should the oil pressure gauge fluctuate with speed


The oil pressure guage will fluctuate with engine RPM. At idle it should be approximately 20 lbs./sq.in, at high revs about 50-60 lbs./sq.in. Hope this helps any concerns you may have. Good luck!
