Please Help. EGR Flow Malfunction P0400
My SES is on so I took it to AutoZone for a scan. Its showing P0400, EGR Flow malfunction. So I took off the EGR valve and used carb cleaner, cleaned it. It was not really dirty at all anyway. I then let the car idle after I put it back on, and pushed in the diaphram and the car almost died...So that means the EGR valve is working fine correct?
I reset the computer and the code still comes back, so what else should I do? Or could the EGR valve still be bad? Solenoid or what?
Thanks
Matt

Havent got around to checking the MAF yet, but I will asap. The car sounds like it is misfiring at idle, but its only throwing the EGR code. I just fixed a misfire from a bad plug.

LOL, well I replaced the EGR valve along with the solenoid, and that fixed the problem. I guess there was some recall on the EGR's for 96-97? Anyway just thought I would reply for if someone searches for this in the future, there are many threads that came up in a search on the camaro forums, but almost nothing here.
