Yesterday I installed my new Diablosport chip and it cause alot of engine problems. First time I installed the chip, no crank. I went back and cleaned the connectors even more and still no crank. I got sand paper and sanded down the connectors to see if any clear coat might still be on there and still no crank. My old chip worked fine so I don't know why this was a problem. I did this over and over again and the truck would not start. Then when I went to install the old chip (hypertech) It started then died halfway up the block. I ended up driving it home with out any chip. When I did get it started though, (with no chip), the over drive was not working (the light was flashing on and off) and the car would accelerate and without changing gears or loosing rpm's the engine would just get really weak like some of the spark plugs weren't responding. And the shifting was hard enough to give me whip lash. Has anyone ever had this problem with a chip before? What should I do? Is this a bad chip?
