1999 Toyota 4Runner Limited 3.4L MIL Lamp on
Posted to Asian Driveability on 6/7/2004 9 Replies

My question for the Toyota guys out there is it normal to have a dead A/F sensor and still have other problems. 25-40 miles on the freeway is what it takes to set the CEL again. Oh I did look at the MAF and it appeared clean however I did not have recognizable...
