Make sure the clamps on your MAF are tight, and all the other connections for the intercooler all the way to the throttle body. If one of them come loose, the car will sometimes act like that.
Im leaving really really early in the morning, meeting up with some non Mazda people. If you want to roll out, meet me at Hooters 1960 and 45 at 6 AM. Bring your coffee...lol
Im still going, I don't give a damn who backs out. Ill roll solo if I must. That would be funny if the only Houston guy up there "use" to drive a Mazda.
