It's already had a tune up and the egr valve has already been checked. What else could it be? Please help.

Well lets see
Fuel pump
Fuel pump pressure can be fine at idle but starve the injector when under load
A plug ed fuel filter will also cause this.
Low transmission fluid will allow the trans to slip and thus no power
Take it to auto-zone and have them scan it to find out why the light is on
Hope this helps you and thanks for your question

There can be a few potential causes. The easiest thing to do would be to go to your local auto zone, advance auto, or similar place...they will hook it up to a code reader that will tell you what's causing the problem and tell you what it would cost to replace...and even print up install directions.
On a '93 vehicle, my knee-jerk guess is a bad oxygen sensor, but there are other possibilities. Have it checked out.
Hope this helped.

What the dealers don't wanna tell you is that sometimes, when vehicles get that old, the computers can get kind of flaky and that causes service engine light to come on, even though everything's fine. I had an old Dodge van and a Chevy van that both went for over 50,000 miles with their check engine lights on before I traded them.

Plugged catalytic converter.
Before you did the tuneup, the motor may have been misfiring. Unburned gasses and fuel may have been collecting in the catalytic converter. This would cause it to heat up allot more than normal. The materials inside can melt, closing off the passages inside causing back-pressure.
The back-pressure would cause the engine to not expel the exhaust gasses efficiently, causing loss of power.

Get it to a rapid lube place and pay them around $50-$70 for a transmission provider (they alter the fluid interior the pan and replace the clear out), If it nonetheless won't pass into equipment, you're able to desire to have the transmission rebuilt or get a sparkling one.

I hate to say it, but it looks like ol' Bessie is dying.
Are you sure it is not a trans problem? Are you losing power or slipping gears?
Sorry

Jack up the radiator cap and install a newer vehicle under it.

Dying battery and/or bad oxygen sensor.
