So yesterday I started my car for the first time in about 4 months. I did the timing belt, installed a FMIC, installed a new MAF and ISC, and replaced the old beat up BISS. So when I started my car up, the MAF was making a very weird beeping noise almost as if an alarm was going off and I am not sure what in the world that is
. Also just to try it, I started turning in the BISS to set the correct idle. Now I know that you must ground the TPS and the ISC, but when I turned the BISS the idle dropped as if those sensors were grounded.
So my questions are what could that beeping noise be from my MAF? And also with the BISS being able to be adjusted does it mean that my TPS or my ISC are malfunctioning or possible not function at all?
