I went and bought a code scanner for my 95 Mystique and these are the codes I got.
KOEO
335 EGR sensor circuit
551 Idle air control solenoid circuit fault
KOER
332 Insufficient EGR flow detected
Just me or does my EGR need replacing? With engine warm and running I took the vacuum hose off of it and no change. Unlike old EGR's I can't try and push the diaphragm to see if it is working. And I don't want to buy a vacuum kit for it if I don't have to. Any ideas, thoughts, or comments? Thanks in advance.
