I have been running a thasher 108 chip for 009s for the last couple weeks and when I went to re-install the 92 chip the car would idle really rough, miss, the check engine light would turn on and scanmaster would not operate. I did not even want to drive the car scared i would damage it. I thought maybe I installed the chip incorrectlly and reinsalled it and it still was horrible. I thought I might of forgot to unplug and replug the orange ecm wire at the battery but I did it correctly. Lastly I reinstalled the thrasher 108 again and it is perfect? Any suggestions? Thanks
