How many miles are on the vehicle? when was the last tune up? it could be the throttle positioning sensor, or EGR.
Thanks,
Lee

I have a rough idle at low rpm almost feels like it wants to stall once it reaches normal operating temp it improves some what I think its the EGR or spark knock 2000 Ford Taurus 3.0L V6


It could also be a vacumme leak. A quick way to check for that is to starting fluid around hoses and gasket areas. If the engine picks up speed when you spray around the engine and not directly in the throttle body, you have found your leak. I also believe these cars have an idol air control valve or IAC that might need to be cleaned or replaced. Check your spark/coil wires while you are checking around.

I can't find the location of the crankshaft postion sensor in my 2000 Hyundai sonata


My online Sonata manual shows these possibilities, but does not identify which applies specifically to 2000 Sonata.
Also, when you talk to the dealership parts counter, you'll need to know whether your 2000 Sonata is (a) 4-cylinder 2.4L MFI DOHC engine, or (b) 6-cylinder 2.5L MFI DOHC engine.
Its easy to tell - just count your spark plug wires.

-- begine excerpt from 2000 Hyundai Sonata Repair guide --

The crankshaft position sensor is located next to the flywheel.
The crankshaft position sensor is located next to the flywheel/torque converter.
The camshaft position sensor is located on the engine near the timing belt cover and under the upper radiator hose.
The crankshaft position sensor is located on the driver-s side of the vehicle, down by the lower radiator hose.
The crankshaft position sensor is located on the engine near the crankshaft pulley.
The crankshaft position sensor is located at the front of the engine near the timing belt.

mcdevito75 here, Sounds like the idle speed motor or the idle speed sensor is no good. Your local shop can check this out for you.

2000 Hyundai Sonata jerking and causing poor performance


The turbine shaft speed sensor can cause this problem, It is also know as the transmission input shaft speed sensor. It will cause the transmission to **** and also stick in 3rd gear, which wound cause slow acceleration.

3rd gear help please!


I have a 2002 Hyundai Sonata and I had the same problem. But mine would always shift into 3rd gear and STAY there until I turned the car off. I took it to a Hyundai dealer and he had to rewire a speed sensor on top of the transmission. Apparently a little animal got up in that tight little spot and gnawed on my sensor wires. The car has run fine since. To make a long story short, it might be your speed sensor on your transmission.
