HI, I'm new here but I am familiar with iATN if that helps, I have a 95 Continental that belongs to my parents that I have been chasing far a year or so. This thing keeps lean mix codes for banks 1 and 2. It also keeps a BARO reading of 147Hz. The BARO reading I know is wrong due to the fact I am near 1000' above sea level. I tried cleaning the MAF and then replaced it with a "new" (reman) unit from the dealership. I still have the same readings. I tried running the WOT 3 times and trying to reset it after the new installation but still the same reading. I am about to the point of pulling the intakeand physically looking for a vacuum leak even though I can't find one anywhere. I did replace the IAC valve a few months ago due to the fact they complained it was stalling occasionally with a low idle. This was also purchased from the dealer. I did notice the other day after a hot soak I do have a definite misfire problem. This thing acts like it is running on 5 or 6 cylinders until you limp it back out on the road and get up to speed. Once you get it moving through the air I guess whatever is causing the problem cools back down. I did have someone say they had an E-series acting the same and it was a camshaft position sensor that repaired his but it was just a single overhead cam 5.4 not this sual overhead cam 4.6. I would try the camshaft sensor due to age and mileage (170000 miles) but I don't like to just through parts at one. I've already done that enough on this one. If anyone has any idea which way I need to go I would really appreciate the help. Like I say, this is my parents car and I would really like to repair it if I can. I have over 20 years experience on diesels I just need a little help on this one. Thanks.
