meow, cough, Cough!
 
I hope my cats are clogged, tell me, i lost probably half of my power, no acceleration, car shakes, muffler shakes much more, not burning oil or coolant, spark to all plugs, i can hear both rotors spinning when i unscrewed the plugs, and i did the atf trick(sorry). I really hope its a clogged cat, and not a blown seal. Another thing i noticed is when i downshift or just let go of the gas the car slows much faster than before. When i also put the car in neutral, the revs seem to completely stop and falls to 1k when it catches rudely. What does it sould like?

Thanks in advance, Matt

A problem :).

Ok seriously, put your hand behind the muffler while its running. Are you feeling a good amount of exhaust?

Unbolt the cats and see if it runs better.

Check your fuel filter too. Might wanna do that first cause its easiest :).

whats a good way of going about taking off the cats cause mine are rusted solid?

An easy way to check for a bad seal is to pull your plugs and listen.

Take the leading plug out of the rear rotor and turn the engine over. You should hear a strong SPFFFTT sound over and over. replace that plug and repeat on the front rotor. If you hear a sound like SPFFFFT blup blup. you got a blown seal. You will know when you here it.

By the way, you should make sure the spark plug wire is out of the way when doing this. You will be spraying atomised fuel out of the plug hole while this is going on. hang it outside of the fender or take it out and cover the coil with a towel.

Good luck,
Mike

Dont hear that too often :). Of course, I guess it is better than the alternative...Just think of it this way, if youre engine is blown, you can get a nice street ported replacement :).

oh but i am poor right now, so very poor, i'm 16 going to school working 8 hours a week a best buy, and paying a arm and leg for insurance and gas, it doesn't add up in my favor

I actually checked for the "strong SPFFFTT " sound and i heard it from both rotors, but i also tried starting the engine with just the rear rotor, and it started but when i tried starting it with just the front rotor, it would just turn over, is this normal or a bad sign?

Just unbolt the exhaust right after the manifold and start it up, it will be loud as f*ck, but it will either fix the problem right away, or eliminate one reason it's not working right. Ask around(parents friends, relatives, whoever) and see if you can borrow a normal compression tester form anyone, screw it in, hold in the release valve, and watch for 3 equal jumps. The normal comp testers will not give you a precise reading, but it will easily tell you if an apex is blown or not. 3 even pressure spikes, it's fine, spikes not even and you have problems.
