missing under load under 2k - ZR-1 Net Registry Forums

Ok so I think I no what my answer is going to be besides big money, but I want to ask any way. I have a miss when my car is under load below 2k-ish on the tach. It felt a lot like a bad plug wire. So I replaced the plugs, and wires, no fix. Then coils, I blew a vacuum line so I had to pull the plenum anyway, nothing. Next checked the fuel pressure and delivery, perfect, and I replaced the fuel filter. Then I cleaned the fuel rail and injectors with 3ms aerosol cleaner (run the car off the cleaner) and added the fuel additive like 3m says. Then map sensor, lastly throttle position sensor. Nothing has worked. A lot of the stuff needed to be done; my car was sitting for the better part of 2 years before I bought it. I think at this point I need to suck it up and buy some new injectors. Dose any body have any ideas?
