cold air induction problem??

sup guys.

Newbie here and just wanted to say hello. Got a little problem with my 94 GT. I put on a mac cold air induction myself a couple months ago and ever since i put it on, my power has gone down significantly. 99.9% sure I did everything right. Car has a lot of miles on it (145,000) but I found it interesting that the engines power started going down after the mod. Has anybody ever heard of such of thing, or know of something I could have done wrong??? Now it just hesitates real bad, and the power loss has seemed to gradually increase as time has gone by. Any help would be appreciated!

Sounds like a dirty filament of the MAF meter.

Thats what mine did when the MAF went bad.

I think you guys are both right. Im just a little puzzled why it went bad after the kit went on. I'm assuming it was fine before. Double check your connections make sure everything got plugged back in also.

Also triple-check every connection, if there is any air at all getting past the MAF it will not run right.

edit: that didn't sound right, I meant if any unmetered air gets in behind the MAF it won't run right.
