Before cleaning my AFM, my 84 ran REAL rich, would idel for a maybe 30
seconds then spit, sputter , catch it's self then idel for another 30
seconds. It also drank gas like it was going out of style. I removed the top
and measured it at the ECM plug and at rest got 500 ohms and as I moved it
upward the readings went wild about 900 ohms then setled back in at 1100 and
upward. When it went wild was where my mprblem was. I cleaned it real good
with electronic cleaner and a cotton rag. there's a cold start air regulator
under the air cleaner that maybe your problem.
