My car is a 96 Breeze with 2.0L & Auto trans. I have a pinging issue. I had found out that the EGR valve was not working. I checked the valve itself, the transducer & the solenoid. All check out. Even continuity from the PCM to the EGR. Here is the odd thing. The EGR will work when I unplug the connector from the solenoid. It throws a code but the valve works & my pinging stops. When I plug in the connector, the code clears & the EGR no longer works. Any ideas? Could this be a bad PCM? Is there any way to check it? I did try a new valve & it made no difference. Fortunately the place I bought it allowed me to return it. I can't block it off because I start pinging real bad when the EGR is not working. I am pretty well stumped.
