Thread: Car saying reduced engine power.

This just happened tonight. I was driving on the bridge and gunned it like I always do at night ,but this time my car said reduced engine power and turned off 10 seconds later. I pulled over trned off the car completely and tried turning it on and nothing, just kept turning over. I stopped for about 2 mins and she started back up with a bad idle and a check engine light. The car drives fine with regular throtle.


So on the way home I try to see if the problem would spur up again so I let her rip and sputter sputter sputter reduced engine power then loss of power. So I'm like wtf. I get home an notice I am showing no vacume pressure on my vac/boost gauge. I dont have it plugged in to light up yet so I couldnt tell when I was driving.

I'm going to see what I can do in the day time but would anyone know what it is directly.

Mine did that a while back and it ended up being a wire was grounded. I don't remember what wire it was, might have been the alt wire

Ok so in the morning I did a little looking around and found what it was


the part that connected the rubber cracked and came off. Hard to belive that little thing can kill my car lol

I replaced it, drove the car a little bit, romped on it and it was totally fine and the check engine light was gone

Isn't it ****ing great when it's something simple like that??

Glad to hear it was a quick fix and not a PITA.

get a better vacuum line and it won't just pop off under high load like that.

Right under supercharger snout. Follow all your lines.
