check and make sure that there is no vacum leaks, such as any broken hoses especially the duct hose from the throttle to the mass air flow sensor , other tha that you have a defective idle control valve

What is causing the fast Idle and slowing down


well gee, there are 50 reasons.
did you scan the PCM yet, if not ,why not?
when the idle surges, that means.
NO RPM ranges stated, if super low rpm check EGR.

1: engine lean and ISC dead, or cant handle the huge engine power drop..The PCM can even make this worse!, buy hunting the ISC to find spec, idle and failing... to...
2: or any of 50 other things causing huge engine power drop and PCM can't maintain idle controls.
super lean burn.(bogging)
super rich burn, misfire for 50 reasons.

i cant hear your engine,nor feel it, or see it shake from gross misfiring.
no can i drive it and see/feel power loss,
can I?
asking net bunny's this (blind as bats)
is "OVER THE TOP" no?
so here , ill toss the dice for you
and guess gross misfiring.
ever get a tuneup this decade, if not bingo , no?

and the others...

link even has the 50 cause list, to show the futility of guessing!
we do 1 to 10 tests. and find it.
for sure.

as you can see EFI systems are complex.
gue$$ is not only expensive but can net you 2 problems easy.

I have 200 Toyota Avalon, Recently I change a transition fluid , it is a little bit over on the stick , Know when i go up on the hill it slow down , what could be the reason


The question is, Does the engine maintain it's rpm's or does the engine actually slow down. If the motor keeps the same rpm while going up the hill but the car slows down then that indicates that the trans is slipping. If the engine slows down at an abnormal rate that could be a compression problem due to high milage

Why does the engine shake when slowing down?


The engine will shake when slowing down, because releasing the accelerator drops the rpm of the engine immediately. The engine only "knows" it has slowed down and will shake the same way if standing still.

There are many reasons for the shaking. All are due to needing a tune up. Poor timing, plugs, wires, cap, rotor, etc.

If you need help fixing something, give me a call.

Slow acceleration, high rpm


This sounds normal to me! The engine will read that rpm when accerlerating lightly. It is the stall of the torque convertor. The oil pressure will always be higher when the rpm's are higher, or when the oil is thicker - cold.

Virbration? That is a different story. Oil won't cause that.
