So, the other night I had my airbox off to check some things out, getting ready to do the cam follower and install a catch can, and when I put things back together I forgot to hook up the MAF. The next morning I started the car and drove several miles, kind of slow because it was a cold morning in city traffic. I didn't notice any problem with the way the car ran and didn't get any CEL's. I didn't realize the car would even run with the MAF disconnected. Does anyone know how this is possible? Shouldn't it have least thrown a CEL?
I woke up at 3 am the next morning and remembered that I hadn't connected the MAF. It is hooked up now and the car is fine.
