My car has a strange running issue where it seems really fast, then falls on it's face, then fast again, etc. I have no codes currently and the following may not be related but I think it probably is.

When logging my MAF sensors I noticed that MAF 1 registers about half of MAF 2. For instance, at idle MAF 1 is around 2.5 g/s and MAF 2 is around 5.0 g/s. As I rev the car it is about the same 1:2 ratio. When MAF 1 is at 9 g/s MAF 2 is about 18 g/s. These numbers are approximate. I swapped MAFs and cleaned both of them while out with MAF cleaner. When I logged again I was getting the same readings on the same channels. So I can rule out the MAF sensors themselves. I smoke tested the car a few weeks ago and only noticed some smoke near the intercoolers so I replaced them with SRM units. I also installed Apikol MAF seals and replaced all of the small hoses on top of the motor.

I would imagine at this point I am looking at either a MAF sensor wire issue or an air leak somewhere. One of my MAF sensor connectors is broken where the wires feed through it but the wires look ok and there is no apparent damage. I have not tested continuity to the DME yet. One other bit of info that struck me as a clue (i'm just not sure what it means) is that when I rev the motor and then take my foot off of the throttle one MAF sensor--#2-- drops back to the 5 g/s in a linear and normal way where as the other drops to 0.0 before creeping back up to it's questionable reading.

Any thoughts here? And which side is #1?
