For some reason, my Purple 93 T/A won't run with a piggyback adapter and chip anymore. It was fine until last Sunday, when I took it out and put it back in. All I did was read the chip to look at the tune. Put everything back together, and I get crap. So, I order a new chip, and reburn the tune. Nothing. The car runs fine with the stock style chip in it. If I hook the stock style chip in to the piggyback adapter the way Madwolfs' directions show, the car won't run. If I flip the stock style chip over, the car will run, but it will be hesitating, won't rev past 3K like there's a rev limiter, and the SES light stays on.

I don't get it, but I really need some help here.
