    Speedometer cutting in and out

    My speedo is cutting in and out and the engine misses for a second when it happens. The car still runs but sometimes the speedo goes down to zero while driving and then kicks back in. Anybody ever seen this before? Seems like an electrical glitch.

    Vehicle speed sensor would be my guess. MTX or ATX?

    The engine and gauges are both loosing power for a second it seems. I would think the battery would act as a buffer to sudden power drops. That makes me think something is wrong with the battery and probably the alt then since the output is cutting out. One last thing it could be is a short. There was a recall about a wire that could rub then short out but I don't remember exactly. Just check the battery and alt first. If they are good I suspect a short somewhere. Anyone with more detailed advice?

    I JUSt fixed this problem todaY Actually. At first i replaced my VSS to no avail. I was having the same issues. the speedo cuts out and engine acts up. and tranny wouldnt shift right. i was all worried it was something serious. turns out it was my instrument cluster. They are forty to fifty bucks on ebay and it isn't too hard to replace. changing that fixed everything. good luck buddy

    If the engine is cutting out, it's most definitely electrical. Vampieralla's car was doing that, and it turned out the main power wire from the alternator to the battery was rubbing on something and shorting out; it almost caused a fire.
