I have a 1997 Taurus, just bought it, I can start it up, takes a lil more cranking than I think it should rough idle almost dying, then push on the gas and sometimes it completely bogs down and dies or some times it take forever to rev up to 3-4k then holds and then I feel a***** in the motor and it falls down to 1500 or trys to die. Sometimes after it does that it wont start up for a half hour or so. Also, no check engine light or codes up. Anyone have any ideas?
Thanks, I'll try the sensor, I have spark, fuel, and air at all cylinders, the plugs looked good the wires seemed to be delivering a good spark. The oil did look a little thin possible gas in it. I seems like a sensor is what is kicking it back and forth, I'll put a sensor in the next day or two and check back with you!

Don't forget a simple vacuum leak can cause hard start, also the idle air control valve! Get a can of spray Throttle body cleaner, start the car and spray around, pay attention to vacuum lines and manifold, if the idle changes, you found a leak. You want the engine running and spray on the outside but do direct the stream onto the hoses, if it is a vacuum leak, the engine idle will change speed, then you have detected a leak, repair the vacuum leak and see how it runs!
Keep the spray away from the exhuast manifolds. Fire hazard.
