Egr valve 94jimmy

i have a 94 jimmy and it was running a little rough the other day. the service light came on , then went out. i checked the code and got a 32 (egr)

i guess i’ll try cleaning it before buying a new one, but i also noticed on the dash my elec. is high, like around 17…

what do i do?

I dunno about your high volts (I assume you were referring to volts indicated) …but I’d get a legit VOM for verifying it.

The EGR is typically changed out in these cases. The return rate on cleaned units it too high.
