Hi all,
I am hoping you can help me out as I have been searching on this topic for a while and not yet found any definitive notion as to what my car's issue might be. I have a 2002 Panoz Esperante, which powered by a 2001 Cobra engine and most of the same drivetrain. My headaches with the car started a few weeks ago when I ran it up near the red line under WOT and suddenly I had a CEL (P0190). The car itself drives pretty well, though there are a couple of unsettling issues: hesitation / bucking around 1800 RPM (but its done this for a while) and the revs are much slower to drop between shifts than they used to be (hanging for 4-5 seconds, this is brand new since the CEL). Based on the searches made so far, I have already replaced the FRPS and the IAC. Certainly there are some unknowns, chief among them the supercharger kit and what I suspect to be a bad tune, but the high revs is just really bugging me. Just thought I would ask before I take it to the shop and make sure there isn't some cheap stone left unturned. Any ideas/help is appreciated.
Thanks!
