Hello all. I have developed a problem only several hours after doing an oil change. The Mazdaspeed protege is only running at 3 psi now. I've been getting some advice from some fellow friends of mine and told me to check the boost controller and wastegate. Do you all have any other suggestions on how to fix this problem? Any ideas of what is causing this? Any help is very much appreciated! Thanks!
