My Grand Marquis is acting up again. It is difficult to start and when
it does it idles very low and almost stalls. Afer a few minutes it's
okay but after it warms up and I'm on the highway, it pings.
Last year I replaced the idle motor because of similar problems. If
it's the same problem,can expect to replace this part every year?
Anyone know wat the hell is wrong with this car?
Thanks for your reply. I'm no sure what the MAF is. Is it the air
filter? The idel speed control was replaced by my mechaninic and I
assume it came from a decent auto parts distributor.

It's located between the airfilter and throttle body. It measures air mass
into the engine for mixture tuning purposes. If it's dirty it will give a
false low reading, which will result in less fuel to actual air, thus lean,
USUALLY dirty MAF has little to no effect on idle speed, but may cause
stumble on acceleration from idle under load, like at a light.
Idle speed control only controls the engine speed by adjusting air admitted
till speed is correct.
Yeh, I'm a Krusty old Geezer, putting up with my 'smartass' is the price
you pay..DEAL with it!
The MAF (Mass Air Flow) is located right behind the air filter. On my
1999 Grand Marquis LS, it's right behind the square plastic box, on the
Yours should be in the same location.it's a plastic pipe going to the
engine's intake, and has a connector on it.
