Air mass meter 200 1983

posted by  someone claiming to be pandrew6l on  Wed Oct 15 06:20 CST 2003 [RELATED]

83 DL with LH 2.0 fuel injection with 121k mostly from city driving. The car gets poor milage now (13 mpg in city) and lacks power. I have two questions: 1) is AMM platinum wire resistance ( terminals 6- yellow/green and terminal 7 white/red) of 4.4 ohms acceptable ? Bentley suggested to replace the AMM if resistance is outside 3.5 to 4.0 ohms. 2) Bentley also suggested when replacing the AMM, you must check/adjust idle mixture using a dwell meter or Volvo special tool 999 5280. Is this necessary ?
From the prior post, someone suggested R/R the AMM only takes 10 minutes and is a matter of turning a few screws. Thanks, Andrew
