Hey guys--
There is tons of info here on the bird forums, and I have found it useful many a time. However, I was unable to find what I was looking for this time. For the past couple of months, I have had a CEL on the 97 w/3.8l. I went today and had AZ pull the codes to see what was going on. I got what I expected...pretty much.
I got codes showing all FOUR O2 sensors bad. The only code I recall at this point is P0171, bank 2 o2 sensor, but all four of them came up. From what I have been reading, it seems that this is a very unlikely occurance, especially with only 82 k on her. So, in further research, I have seen where the MAF sensor may be to blame. I was wondering if there was a way to test the MAF using a DVOM and exactly what that procedure may be. I do not want to go throwing money at her only to find I did not fix the prob.
I would appreciate any info you all could provide me with.
