I can't help but wonder because your engine floods so much it sounds like a faulty fuel pressure regulator. The O2 sensors are mounted just behind the manifold and a little forward of the cats which there are two, one for each bank. It seems strange that a faulty O2 sensor causing the flooding problem like you described. They might allow a rich or even a lean mix depending on what the computer allows in fault mode, but flooding like that seems like a bit much > Good point. I don't have any experience with Isuzus, really. I mentioned the O2 sensor only because it's a common failure and it's easy to test/replace. Most older cars probably need a new one anyway, even if they appear to run fine. _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com ________________________________________________________________________ Check Out the new free AIM(R) Mail -- 2 GB of storage and industry-leading spam and email virus protection.
