EGR Valve

WARNING: This page is about a different car, the 1996 Suzuki Swift. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect EGR vacuum hose and attach a hand-held vacuum pump to vacuum hose port. Apply about 8 in. Hg to EGR valve while checking for smooth operation of diaphragm. Ensure diaphragm maintains position without losing vacuum.
  2. With engine at idle, apply vacuum to EGR diaphragm. Engine should idle rough or stall. If diaphragm retracts and engine RPM does not change, remove EGR valve and check for clogged passages.
