1. I'm using H9DCO plugs
2. I've cleaned the ICV and replaced, but upon initial visual inspection it appeared clean.
3. ICV exit hose is cracked where it connects to ICV. I've reassembled and placed a clamp around the hose until I can purchase a replacement. Idle is slightly rough.
4. I was unable to locate EGR system. I need to do more research, but can anyone confirm if the '89 260e has an EGR valve.
5. I was unable to check lambda - need to pull my voltmeter out of storage.
6. Last, I have never reset the timing in my vehicle. Can someone please walk me through the steps. I did a search on these boards but was unable to located instructions.

Thank you.

Steven
