Hi All. I recently had an AEM Cold Air Intake installed on my 2011 Toyota Tacoma. Shortly after install my check engine light came on. I got the code read and it was p0101. Since then we've cleaned the MAF, made sure all cables, hoses, etc were connected properly. Finally I replaced the MAF thinking it shorted upon installation. That worked for 3 days, then I got the p0101 again. It says the truck is running too lean. I've contacted AEM and all they wanted to do was refund the intake, provided no help or feedback at all. Basically said they didn't know what to do. I do live in a very cold area, below freezing most of the winter; however, I do ensure my truck has ran for several minutes and the engine temperature has moved off cold before running. Has anyone encountered any problems such as this and have any trouble shooting tips? Obviously, the intake was installed correctly, proper model for the truck, etc. Thanks in advance for any help.
