When I come to a stop, my engine idles at 1250 rpm. 3 or 4 seconds after, it drops to the normal 800 rpm.

Anyone is experiencing this?

My RPMs only bounce around when i'm in P. They're always steady when I'm at a red light in drive gear (as far as I can remember anyway).

show or fast it doesn't matter, the idle sticks up.

If I just rev it I got no problem. But if I'm moving and depress the clutch, it will idle at 1200 until I come to a stop.

My guess is that the Speed sensor has something to do with it....

My second guess is the TPS . I'll check the TPS fisrt.

Well night, I also wondered if the coolant could be the problem.

I DO hear the coolant bubbling in the heater core when I start the car in the morning (like there was air in the system)

I need to do a coolant flush anyway and I planned to do it this week (I got more water than prestone as of now. Cold nights now scare me :( )

my car did that... i was told it was normal... it does fall within the specs for high idle, so that's what i figured it was

My car does that now.
If I can remember, it didn't a while back.
I don't think it's the throttle cable either. Must be something else.
