Been getting the "SES" light on my 94 for a couple of years.Runs fine,just annoying.

Getting trouble codes #75,76,& 77 saying all 3 EGR solenoids are bad. I installed a new EGR valve when it first started but still comes on every time I drive it.Usually as I let off the pedal to come to a stop.

Also got soft codes saying:

Quad driver 1--bad

Quad driver 2--bad

Quad driver 3--ok

Quad driver 4--bad



Don't have a clue what this is. Like I said, it runs great.I'd just light to stop the light.

Don't wanna just pull the bulb!!

Any ideas?

Thanks
