It's most likely the crankshaft position sensor and cost about $45 to $50. I had a similar problem about 6 months ago and replaced it and so far no problems. The sensor is located right by the oil filter and the other end goes all the way to the top behind the upper intake (driver's side).

Yes, it's pretty easy fix and I would say about an hour all together. You may have to cut the old wire where it gets pinched by the oil cooler lines and send the new one around it. Also, add extra aluminium foil (extra heat shield) around the new wire where it gets close to the exhaust pipe.

Well here are the parts she need's to buy.... and please let me know if they are the wrong parts

1. 2 O2 sensors they are
Bosch - Oxygen Sensor
Part # 16065

2.CranKshaft Position sensor
BWD - Crankshaft Position/Angle Sensor
Part # CSS79

3.Speed Sensor.... now we are lost with this one is there a difference between an ABS Speed Sensor and a Speed Control Sensor????

and each part was found at O'Reilly Auto Parts on O'Reillyautoparts.com

There is a speed sensor for each wheel (wheel speed sensors), and a vehicle speed sensor (for PCM and speedometer). No such thing as a "speed control sensor".

How do you know the O2 sensors need to be replaced? How do you know there's a speed sensor problem?

Were the codes pulled???

Which codes came up?

I didn't pull any codes her dad did and he stated that the O2 sensors need to be replaced, which I think they might need to be cleaned. I know from the jump that she need with the Crankshaft Position/Angle Sensor because from what I seen it will drive about 3 miles and shut right off..

probably he misplaced something or maybe some wire is not connected.

Another possibility might be bad coils or have to relearn throttle body in case he removed it or maybe a vacuum leak somewhere.

----------

also, try unplugging the Mass airflow sensor and see what it does. It could be a MAS sensor too.
