The starting problem could be head gasket if it got really hot..... black smoke wouldn't be oil, and gas would stink but not black smoke if it's old, it wouldn't really matter if it had been sitting for 4 months. black smoke is probably caused by a gas mixture problem, or maybe a stuck fuel injector.

98 ford taurus starts runs 5 seconds then dies


Something is disconnected.Is the MAF (mass air flow tube on ) is the MAF electrical part connected in its socket,Vacuum hose to the intake manifold. (Will have a way high idle and you would hear it) Idle air control hook up? Can you maintain a high idle pressing on the gas pedal,if you can the IAC(idle air control) is the problem,other than that some thing is disconnected.

I have a 1998 Ford taurus. It starts fine but then dies and also when slowing down the RPM dropped and it stalls. Can start again, but it dies off pretty qickly.


need to check the idle/air control valve.the valve gets sludged with oily tarnish and moves slowly and can'y keep the car idling properly. may also want to clean the throttle plate , it too can be sludged with the same tarnish limiting the air flow.

I have a 2002 ford taurus. check engine light is on. Auto Zone did a scan today and the error code was p1507 can you please tell me what i need to do to fix this problem.


possible problems

Vaccuum leak
failed IAC valve
open or short
air inlet plugged

P1507 means "Idle Air Control Underspeed Error". It can be most commonly caused by a vacuum leak, a damaged Idle Air Control (IAC) assembly or a stuck IAC valve that needs cleaning. Essentially, your engine isn't idling at high enough according to your computer's programming parameters. Many times this shows up in colder weather as you try and start your vehicle. It will usually die unless you put your foot on the gas pedal and raise the RPM's. I have also read where a clogged air filter might be the problem. I would try cleaning your IAC valve first.

My 2000 taurus does not hold idle, even with engine at normal operatin temp. It started random and now is more frequent. Regards. G.


If it just dies, sounds like the Idle Air Control Valve. If it surges and runs rough, sounds like a vacuume leak, especially if it is the DOHC 3.0L engine, they have several vac hoses that go bad.
