haha the said it was the whole wastegate assembly, like the internal peice of it. the place i took it to said it was just the actuator that was causeing a vaccum leak. ive replaced the maf and the sparkplugs and i still threw a cel. so i just ordered the acuator part at atpturbo.com wich was like 160 dollars cheaper than from them because they have to order it from mazda. so im fixing it and now im gonna have to part with the speed. had it for 5 months and the problems i had were just ridiculous, the guy who owned it before must have ragged the b**** out
