The Se's have a 6 port actuator located on the lower intake manifold. See if they are locked tight or if you can move them by hand.

ya the ports open freely. i dont know whats up with it. i thought they ran like a high 15 sec 1/4 mile

Do you still have the cats on?

MrFC3S

hold the phone, the S3 13Bs have 6ports? I thought they were 4port?

Putting together a check list for you.

1). Verify 6 ports are opening by revving motor and visually seeing them move.
2). If there is no history or it has been 30k since the fuel filter has been changed then replace it.
3). Check and verify timing is correct.
4). Make sure air filter element is clean
5). If vehicle struggles to go up hills or flattens out on rpm and HP then check main cat for blockage.
6). Run compression test
7). Send injectors out for cleaning and testing
8). Verify fuel pressure and volume

1.) I don't think you can "see" them move while just revving the motor while parked, you'll need to put two cable ties on the actuator and slide them to the "down" position, go out and run the car...when you come back to check, if your 6 ports are working properly, the cable ties would have been pushed to the "up" position.

What do you think that I make this **** up,lol.
Yes you can if they are operating properly that's all you have to do is rev the motor to a higher Rpm and watch the actuators.

The ports can be tested also by putting a dab of bearing grease/vasoline on them, taking it out for a run above 3600-3800 rpms where they usually open. If the grease has moved, they have opened, at least partially. Doc is correct when he states that you can see them open by reving the engine.

While the actuators may move freely by hand, that does not mean they are opening when the revs rise. I have seen more than one SE where the pipe from the cat is either blocked or broken and not allowing the 6-ports to open.

^ Or if they vacuum hose has layed against the exhaust and now has a hole in it.
