Porsche Crest Momentary loss of power???

The car has been acting a bit strange lately. Sometimes, when on a very bumpy road, I get a momentary cut out of power, the car feels like it hesitates for a second. Once it does that, sometimes the power comes right back, and sometimes it does it a couple of times if the road surface is really bumpy.

I plan on checking all the electrical connections this weekend, was just wondering if anyone knew of any grounds that could be causing this. I thought maybe the overboost sensor (since that's what it feels like) wire might be a bit loose, and I have a little jumper that the previous owner used to ground the wire to the intercooler with (bypassing the overboost switch), so I connected it and then reconnected the switch, so the wire is a little longer to rule out that.

Any thoughts or reccomendations?

Bill

you may try connecting a test light via jumper wires to various places, fuel pump in engine compartment, fuel pump relay, etc. maybe you could tell if it's loosing fuel that way. It could be the fuel pump relay, or whatever is triggering the relay... It's most likey fuel as you didn't mention the tach acting up... Although that lead me to a brain fart on your situation so here goes... When whoever installed your electromotive for the PO, did they leave the stock ignition sensor and control unit in place and just remove the coil and such? that would probably have been a smart thing to do. I wish I'd thought of that years ago the only time I twinplugged a c2t. oh well, just a thought good luck!

Thanks guys. I will need to take a picture for you Mike, as I think a lot of the stock ignition stuff is in there. I did find a connection that was loose, but will spend some more time tomorrow and will take some pictures.
