1993 SL2
Default Engine light off and on while driving.

The engine light of my '93 SL-2 comes on 2 seconds after I start. it turnes off while driving but every time on idle or with very little to none thottle, the light comes on.

I know I have a code 26 and 32 (EGR and Quad driver) and have cleaned already the EGR valve. Can this be something else such as the o2 sensor??

I need to get emissions done ASAP but can't because of this issue

A code 26 and 32 together usually indicate a problem with the EGR solenoid.

Correct, that was my understanding as well. However, I have replaced the solenoid but the problem did not went away. I know the cannister as well as the valve is an option.

Are those three items the only ones in the EGR system?

Theres only the EGR valve and the solenoid. The charcoal cannister is part of the EVAP system.

So in this case cleaning or replacing the EGR valve should solve the problem I guess.....
