I should have given you the reason for the series of tests. The test is to eliminate potential problem with your transmission solenoid.
In your case, there is nothing wrong with the engine. The engine is doing exactly what it is supposed to be doing. The transmission however, has a problem transferring the power to your wheel. I believe it lies in you TCC (torque converter clutch) solenoid.
Basically, your automatic transmission is not shifting down automatically. When I asked you to drive with the OD off or at 2nd gear, you kind of bypassed the solenoid and manually shift the transmission.
I guess now, it kind of depends on you. Do you want to spend money on a 16-year old car? Although, point to keep in mind, you only have 130K miles. You should have a lot more life from that car. My '95 B14 has over 245K and it still runs very strong. (Knock on wood) It has never breaks down and left me stranded.
What have done for years is that I drive with the OD off in the city, and with OD on once I get to freeway speed.
This TCC is from my '95, but should be very similar to your '93, unless if your have the SR20 motor.
