Car is a 95 v8. As soon as I turn on my vent blower, my car stumbles, the speakers make a big "boomp" sound and my speedometer and tachometer both go to 0 then pop back to their previous position. The ammeter also moves about 1/8th of an inch to the left and then almost back to where it was previously, but now it vibrates which it didnt do before today. The last thing that I did was disconnect the battery to clean the MAF. Thanx for reading.
