Gas mpg has gone down, any input?

Wow, I've honestly never encountered a dead MAF and I've worked on many, many modulars. We've had a bunch begin to read incorrectly or not at all. In those cases, we've checked the sensor surfaces to make sure everything is intact and if so (sometimes the sensor electronics are fine, but the surface is broken due to debris geting into the sampling tube) we simply clean the sensor with brake cleaner and reinstall. I mean, the MAF in my slobra saw more abuse than you could possibly imagine, hehe. I even dropped it once...

When mine was replaced, they made the fatal mistake of giving me the old one. I promptly took it to a machine shop, and had the post removed. The only thing left is the sampling tube. I can't say for sure whether it did anything, but it felt like it did. I know I shouldn't have opened this can of worms again, but oh well.,,,,98

Well, I don't know which style MAF you have, but I know on the 94-95 Mustang GTs, removing the post in the aluminum MAF causes a lot of idle problems and can cause WOT problems without a chip. When you mess with the MAF like that you are causing an innacurrate reading. Run a datalogger with a stock MAF setup and a modified MAF setup and you will see that the voltage reading is not consistent. The guys at SCT freak out when people do this--it really messes with the computer...
