02 Virage TXI. Running rough from 2000 thru 3500 rpm
Hi all, new to the forums here. I just bought an 02 txi that had been sitting for about 3 years. Good compression and ignition. Just replaced the fuel pump and filters in the fuel module. New plugs. Ski only has 52 hours on it and is in nice shape. It starts and idles. Seems to idle a little high to me. About 1100 rpms. Between roughly 2k and 3500 it runs real rough and just feels kinda boggy and the check engine light comes on. Below or above that and it runs great and no light. Any thoughts?

Welcome
Make sure the correct NGK PZFR6H spark plugs are installed, no substitutes.
I am on mobile so cannot type a lot.
Search for info on checking the voltage on white/red wires. Must be checked without unplugging any injectors.
I have a hunch the injector voltage is not stable in the 2000+ RPM range.

Is the voltage supplied by the capacitor or from the emm? I haven't had a chance to check it yet, I'm just learning how this thing works.
Thanks
