i unflooded the engine with the ATF treatment
it was driving fine and the engine was smooth
and tonight i start my engine(3rd time after the ATF treatment)
the engine will surges like crazy
and when i gas, the car is lack of power
the car barely move in 1st gear
anyone know what's happened?
was the ATF did the damage?
or the ignition timing is out? or compression is gone?
plz help

Does it idle ok? Does the tach work? Could be an ignition problem, maybe a fuel problem. Dont freak about the engine just yet.

the tach work and the car surge like crazy when idle and will die off if i don't keep my gas on it

Take your spark plugs out and crank the engine over by hand. Listen for 3 good "PUFFS" to come out of each rotor. This is a free way for you to get an idea of how your compression is. It will help you decide if any of your apex seals are totally blown or not. It is a good place to start when you are questioning your compression. If you get some nice puffs across all rotor faces, then you know that your compression should be okay.

It sounds like a major air leak. Bad seals will not make the engine surge. Look for an air leak.

the ATF might have gotten into your vac lines depending on how you did the treatment. or this could just be a coicidence that this problem happened after the ATF treatment. more than likely the motor is fine.

Cat clogged with ATF?

SF@Rx7

i am possitive the vac lines
because i put the ATF directly into the leading spark plug hole
may be some fuel problem
will put in a new fuel filter and see if it would help

ya how can the cat get clogged with the atf. expalin please , because i dont think its possible

SF@Rx7

i think i figure out the problem
the car surge because the front houing is flooded again
don't know y but i do warm up all the way before i turn off the car
but anyway i am doing my atf on the front again
hope it will fix all the problem
crossing my finger now

Did you change the plugs after the ATF treament, they will be badly clogged with oil.

SF@Rx7

i did i put in 4 relatively new plug in there

here is one question
anyone think it is possible to have only one housing flooded?
i heard from someone said you can push start to unflood a engine
this will be unreal if the front houing of my engine does flooded
because i did drove 30 miles at this condition

Yes. It sounds like you are leaking excess fuel into your lead housing. This is probably the root cause for the flooding issue, as well as the surging while driving.
