Hey guys, I'm not sure if this forum has any rules about jump starting old threads (some forums have lots of silly rules) but I wanted to update this subject. I put working on this on the back burner for a few months, but recently I had some problems with my work truck that could not be fixed in a day, so I decided to take another look at my Sooby. I went to the junkyard found an OEM maf sensor. Slapped it in and presto! Car running strong again! Misfire codes eliminated by changing to a set of NGK plugs. Now I only have to check out the EGR. I just wanted to thank the forum and the guys who replied to my posts. I was skeptical about the aftermarket maf sensor's unsuitability, but you guys were right. Junkyard part that fixed my car for 22 dollars sure beat a $300 aftermarket part that didn't work. I hope anyone else with similar or different problems listen to their advice. They know what they are talking about, either through experience, sheer brilliance, or both!
