CAUTION: When cleaning intake manifold EGR passages, care should be taken to ensure that all loose particles are completely removed to prevent them from clogging the EGR valve or from being ingested into the engine, as damage to system or engine may occur.
1. Remove throttle body.
2. Disconnect vacuum hose or electrical connector from EGR valve, then remove EGR valve to manifold retaining bolts and valve.
3. Remove deposits from EGR ports by hand using a suitable drill bit and screwdriver.
4. Brush small deposits down EGR port into passages, then using compressed air, blow ports clean. Solvents should not be used to clean EGR valve or passages, since damage to system may result.
5. Install EGR valve, using new gasket.
6. Install throttle body.
