I just got through installing the Kenne Bell Boost a Pump with the lethal perf. upgrade and also a MAFxtender. My cobra is completely stock except for intake, and headers + exhaust. The MAFxtender has the bypass plug installed right now until it gets tuned so I figure that’s not the problem. The BAP dial is turned down to 0% also.
What happens is when the car is idling at 700 RPM’s, if I push the window buttons the RPM’s will fall to 500 RPM’s and the car starts to hesitate. It does not completely stall or cut off it will just hesitate until I let up off of the window button. Also when the headlights are on, you can see them get dim when rolling the windows up or down.
Does anyone have any ideas on what this may be or how to fix it? I figure it may be the battery or the alternator. Does it need a new alternator or is this just normal?
