OK, got the input speed sensor for my 2001 santa fe with the 2.7 v6 engine. Removed the air box and thought I was removing the speed sensor but when I disconnected the wire the part was the OUTPUT speed sensor. Not having enough time to hunt anymore I was hoping someone could send me in a more exact location of the part. Thanks in advance.

I wish to adjust the idle tickover speed a wee bit on a 2007 Ford Transit 2.2 Duratorq engine. It is currenlty ticking over at approx 800 rpm and is hunting at this rev. If I could raise it a wee as I do wit my foot on the accelator pedal, the hunting goes out of it.

1997 Dodge 5.9L Diesel automatic. Hunts trying to go into OD or trans lock. Seems to work better in hot weather after about 5 miles at highway speed. Checked TPS. It is well within specs at 1.017 idle and 3.7v at full throttle. Tested voltage response from black to orange. Hunts around 40 mph, where it is supposed to shift, I think.

Rough Idle Have rough idle and/or 'hunting' idle speed (up & down & up & down) on 1994 Mazda Protege automatic 1.8 litre double overhead cam engine. I'm considering removing the Idle Air Contul unit, taking it apart, cleaning it, then re-installing it, because new/rebuilt units are like $300+. Can anyone tell me if this has been done, and if yes, how hard is it, how long does it take, what do I use for cleaner [fluid?], and what special steps should I take in cleaning the inards and rebuilding t

The vehicle fails to start. The lift pump does not presurise the fuel system. Vehicle starts after bleeding is done on the injector pump. vehicle on the road runs perfectly. At idle speed the vehicle "hunts" as if there is afuel starvation. Upon switching the car off, it fails to start again.Every time we clean the tank , oil appears in the fuel.

I have an Audi 80 1.8 petrol 1989. The car starts from cold with no trouble settling to a normal idle speed. However as you drive for a mile or so and come to slow down the engine dies to a extremely rough and lumpy running - barely above a stall. Pressing the accelorator produces no revs and the engine ''hunts'' firing only on a one or two cylinders. Eventually the car will start again and as long as the revs are kept high it will drive again, although when the revs go lower the engine dies aga

1992 maxima. 2 or 3 times a day the car acts as if it is being shut down and restarted very quickly, duration appears to be less than a second, multiple times if I kept pressure on the gas pedal. After trying to look for a pattern, I finally put the transmission in neutral when this happened and disciovered that the engine was actually "hunting" over a range of 1,000 - 2,000 rpm. This happens at any speed , idle to highway cruising. Please help.

2004 545 bmw. when maintaining a speed of about 40 mph, the transmission will hunt back and forth for the proper gear. it just started doing this since passing 80K miles.

My 1998 Series 1 Discovery drives ok but when hot at idle speed the revs hunt and the engine stops. It always starts immediately. I tried changing the air flow meter but no change. It definitely seems worse in high ambient air temeratures. Fuel consumption is truly awful even for a Rover v8, I get about 300kms on a tankful. Any ideas? Thanks
