when im at a stop light and or in park The engine idles unsmoothly.

Im guessing it's idleing unsmooth cause the accleration is going against the brakes.

i did a test on a open road, i brought my car to a stop and let off the brake and DID NOT touch the gas pedal,

my car modaratly went from 0 to 5 mph then from 5 to 10 to 20 then finaly 25 MPH. im guessing thats bad.

and im not sure if thats a sticky cable or what. BTW just got oil chaged today.

Just Wonding what i should i do about it.

the car is a 94 ford temp.

Could be the idle control or idle air control valve. Did they muck around with anything but the oil? I had that part die on my Taurus earlier this year, and it idled all over the place (usually starting high and then dropping without warning, almost enough to stall the engine) and happily accelerated on its own.

It started doing this before i got the oil change. started randomly doing this about 3 or 4 days ago. and it make's a strange noise when i turn off the engine too. kinda like a rotating scrape/hum.

You're going to have to take it to a shop, when it's doing that.

Your car is just old. Call for a tow truck because you might kill someone since your car is all messed up.

I looked into it and found this TSB (Technical Service Bulletin) from '97.

ISSUE: Some vehicles may experience the idle speed
fluctuating when coming to a stop after a cold start

Is this what you're talking about?
