My 1991 KA24DE manual is accelerating really slowly. In 1st through 3rd, it is most noticable. One I am cruising on the interstate, it can accelerate normal though. Almost feels like I lost some torque.
Here is what I can think of:

I know my exhuast is very leaky. Maybe my cat is clogged?

It may need a tuneup. I have only had the car for 13,000miles. The fuel filter was done 5k ago.

The pedal is very stiff and very sticky. Maybe the throttle body is clogged? Could it be that it accelerates slowly becuase the butterfly valve opens slowly?

Search turned up somethign about an AIV valve?

Worst case is I am losing compression, running on 3 cylinders, or I need a rebuild

Any other ideas?
Thanks,
Jeff
