quote Originally posted by mitchjl22: Neils88, you're right. the code was lean. Do you think it was because the plugs were bad, those don't look very good to me. They were the tapered kind to begin with, I replaced them with autolite 104s gapped to .055" . I also got my 3/4" npt tap today. That is what I read is the right size for the passage under the SC snout.

Unlikely that the spark plugs caused the lean condition, usually just a symptom. Lean conditions can be a pain to track down. Often caused by vacuum leaks, dirty sensors, faulty or stuck PCV valves, faulty oxygen sensors, faulty or plugged fuel injectors, low fuel pressure, dirty fuel filters, exhaust leaks before O2 sensor.

You've already changed the plugs, so the easiest place to start would be to do a check for vacuum leaks, change the fuel filter if it's old and use a bottle of injector cleaner to start with, then see if the code comes back.

EDIT: Just scanned up a bit in the posts to refresh myself on where you were...I see you mentioned vacuum leaks and a maybe needing a new MAF...good chance you've already solved whatever was causing the lean condition

Thanks for the suggestion, here's roughly what it would look like, Notice the lip reflection is silver still...


The best thing about plastidip, is I can get them in chrome, and paint them black, when I get tired of it, off it comes, and I have chrome wheels again!
