Yo.

I have a 93 sc400 with about 128k on the clock.

It starts and runs great, but it seems a little sluggish to me. I understand that these cars aren't mega fast, but from what i've read, 0-60 should be under 7 seconds and the best i can do (stopwatch) is 8.7. Seems slow...

I've just finished replacing the spark plugs, wires, cap and rotor on the car but it doesn't really seem any different to me.

Any thoughts on some other stuff I might want to look into?

Please let me know your thoughts.

Thanks.

How is she breathing? Mine has 141k and I manage to do 0-60 under 7 seconds everyday.
Maybe your air filter is dirty or your cats are clogged. Revs up to 6k??
How´s the auto doing? Maybe is slipping...

Auto is a recent replacement that is fully functioning.

What about your exhaust?
How are you launching it?

just did this one today and it def makes a difference off the line...

not sure about the MAF one yet. I would probably only do that if I was going to race someone as it appears to eat up the fuel...

My guess would be your cats might be a bit clogged and or the air filter------- im not sure if the throttle body being dirty can affect performance to the point your talking about ---but i think it would be worth giving it a once over.

Good luck.
