how to test ported egr solenoid, 1994 4.3l, z
I have a code 32 on a 1994 s10, 4.3l, tbi. I removed, cleaned and checked the valve, but I am getting no vacuum from the solenoid while driving. After a few miles I get the code, prob from the comp doing a egr valve check. Does anyone know how check the solenoid, such as voltage and ohm numbers before I buy a new one?
