Hey guys Im new to the Is scene , so I bought a 2001 Is 2 weeks ago and it dosent rev over 3000 rpm is stays at 3k RPM (even if u floor it) and then shifts. I took it to a tranny shop and they sead the tranny was good. One of the guys at the shop told me that is could be my ECU ? does the 2001 is have a separate computer just for the tranny ? And it also had a CEL but whenever i would hook it up to a scanner it would never connect to the scanner any Ideas why ? I just managed to erase the CEL for a little while.
