Question about 1999 Ford Taurus
I have changed Egr valve low flow air control tuned it up changed air filter cleaned throttle changed vac hoses. this is driving me crazy. you drive it one time it runs fine park it come out the next day it runs badly it will buck and race when taking off, then when you stop it will race up then down then die. sometimes when you take off it will sound like it slips and then kicks in but then continues bucking and jumping. Please Help thank you
Lawn mowers have had that problem before and what it was is rust or a object in the fuel tank blocking the flow of gas you might try changing the fuel filter there could be contaminate in the fuel line one way to test that would be to disconnect the fuel line from the engine and aim it in to a gas can and have some one turn the key to the on possition watch the flow to see if it sputters if it does theres the problem , then you should replace the fuel pump and filter as well as the inline filter.

Is it a Diesel?
Camshaft position sensor recall may cover it.
Gas or Diesel:
Fuel Pump and/or relay.
Engine codes could help if Check Engine Light is on.

SOURCE: bucking while idling
Have the upper and lower intake manifold checked. It needs to be a cold start. 2000's are notorious for having the gaskets crack and leak. This may be causing the engine to idle rough at start-up ans somewhat disappear after warming. Winter starts can shake the steering wheel!
P.s. I had it fixed at 65,000 miles (warranty), and am having it fixed again at $120,000 miles.

I'm having the same problem with my 90 2.3L Ranger. I replaced the EGR Valve back in August and the truck ran fine (but the gas mileage was bad) until late December . I knew it needed an O2 Sensor back in August but didn't replace it until last Saturday along with the Idle Air Control Valve, Plugs and Wires. The truck ran fine for a couple minutes then started running like a VW bug! My code reader is now throwing out an EGR failure code, so I guess i'll take the 4 month EGR back and get a new one, and see what that does!

MAF: A Mass Air Flow (MAF) sensor output that causes the PCM to sense a lower than normal air flow will cause a lean condition.
Air Induction System: Air leaks into the induction system which bypass the MAF sensor will cause a lean condition. Check for disconnected or damaged vacuum hoses, incorrectly installed or faulty crankcase ventilation valve, or for vacuum leaks at the throttle body, EGR valve, and intake manifold mounting surfaces.
Fuel Pressure: Perform a fuel system pressure test. A faulty fuel pump, plugged filter, or faulty fuel system pressure regulator will contribute to a lean condition.
Injector(s): Perform injector coil/balance test to locate faulty injector(s) contributing to a lean or flooding condition. In addition to the above test, check the condition of the injector O rings.
EGR: Check for leaking valve, adapter, or feed pipes which will contribute to a lean condition or excessive EGR flow.
Reviewing the Fail Records vehicle mileage since the diagnostic test last failed may help determine how often the condition that caused the DTC to be set occurs. This may assist in diagnosing the condition.
