Last night I replaced my upper intake gasket hoping to fix my idle problems. I noticed it ran a little better but I found when I unplug the MAF connector it smooths out a bit. I plugged it back in and it idled a little rougher. I ran a code scan and came up with LOW MAF VOLTAGE. I cleared the code and tested again. It did not throw the code. Does this mean my MAF is bad or is the problem somewhere else.
